But I Play One on TV

Sometimes, an actor will get cast in one type of part so often that, eventually, all he ever gets cast as is that same sort of role. In the case of But I Play One on TV, the actor is so identified with the role he plays that, when people see him walking around town, or actually bump into him and manage to talk to him, the fans refer to him by the name of the character he plays. It isn't uncommon, for example, for an actor who plays a doctor to be asked to dispense medical advice by a fan he meets on the street.

This problem is often exacerbated by tabloid news sources, especially gossip magazines and "news programs" that concentrate on celebrity and entertainment, who in their stories are constantly referring to actors by their characters' names rather than the proper name of the actor. This is generally an editorial decision, as it can make it easier for the audience to identify the actors involved, but at the same time contributes to blurring the line between fiction and reality in viewers' minds.

Not to be confused with I Am Not Spock, which refers to an actor who's unable to get any part other than the character for which he or she is known, nor to be confused with I Am Not Shazam, which refers to the confusion of a character with the title of a work or with the character's Catch Phrase. Truth in Television examples frequently cross over with both Mean Character, Nice Actor and Nice Character, Mean Actor.

Real Life Examples:
""Mum, he's got a chip in his head!""
 * Harlan Ellison wrote in the intro for his book Strange Wine that he talked with Dan Blocker (Hoss from Bonanza) about this phenomenon. Apparently, Blocker once had a woman come up to him in a supermarket and ask him about how Hoss was. When Blocker replied that he wasn't Hoss and Hoss was fictional, the woman said, "I know that, all I want to know is if he's alright!"
 * Robert Young, who played Marcus Welby, M.D., often said that people would ask him for medical advice.
 * People today associate actor turned U.S. Senator Fred W. Thompson with being tough on crime more because of his role as District Attorney Arthur Branch in Law and Order than because of his career as an attorney and service as minority counsel to the Senate Watergate Committee.
 * There are actually people who think Stephen Colbert really is that much of a conservative whackadoo, including the organizers (and attendees) of the 2006 White House Correspondents' Association Dinner, who were, needless to say, relatively shocked when they found out otherwise. (Though apparently not George W. Bush, given the opening act.)
 * Dennis Haysbert (who played President David Palmer on 24) tells a story about a couple of fans who freaked out when they saw him hanging out with actor Gregory Itzin (who plays President Charles Logan,, on the same show). The fact that the two actors are good friends apparently never occurred to anyone.
 * The late David Jackson was once mistaken by a kid for Olag Gan, his Blakes Seven character, while the actor was shopping in Harrods.

""For several weeks now, we have seen American citizens stranded on some Pacific island. We spend millions in foreign aid. Why not send one U.S. destroyer to rescue those poor people before they starve to death?""
 * Infotainment shows constantly referred to the star of Grey's Anatomy as "Doctor McDreamy". Hey, you... yes, you the guy at Entertainment Tonight! He's got a name. It's Patrick Dempsey! He's only been a fairly well-known actor now for the last 20 years or so.
 * David James Elliott was constantly referred to as JAG during the run of that show. The really stupid part being that wasn't his character's name... it was his character's job. Entertainment Tonight later did a story about Elliott joining the cast of Close to Home. They still called him "JAG".
 * In a guest appearance on The Tonight Show, Jason Hervey, who played Kevin's bullying older brother on The Wonder Years, said that a man once drove up beside him and demanded to know why "he" was always so mean to his brother and why didn't he pick on someone his own size?
 * Another Wonder Years cast member, Alley Mills (Kevin's mother Norma), also a Tonight Show guest, said that a fan once asked her whether she was related to Jay Leno. When Mills asked what she meant, the fan explained, "Well, you're Kevin's mother, and Kevin looks like a young Leno, so..."
 * A possibly apocryphal anecdote about Christopher Reeve: When the actor (before his accident) confronted someone trying to steal his bicycle, the thief panicked and said, "No, Superman! Don't hit me!"
 * Superman tv show actor George Reeves had it rougher, as his younger fans would often try to test his invulnerability. The worst case was when a boy brought his fathers gun to a set see if Superman was really bulletproof. Reeves convinced him to hand over the gun saying that the bullet would bounce off and hurt somebody else.
 * In September 2008, when Michael Douglas spoke at the United Nations about the U.S. financial crisis, a reporter asked him, "Are you saying, Gordon, that greed is not good?" The actor replied, "I'm not saying that. And my name is not Gordon. He's a character I played 20 years ago."
 * It was even worse than that; he was actually there to talk about nuclear proliferation. The reporters derailed it into a discussion of the financial crisis, just because they were talking to the guy who played Gordon Gekko.
 * With the release of the Twilight film adaptation, it seems a number of young fangirls have confused actor Robert Pattinson with his character Edward Cullen. According to the New York Times one girl, seeing him at the Apple store in SoHo, asked him to bite her.

 * In one of his books, Tim Allen mentions that while on a flight one of the pilots came back and asked for actual advice on fixing up his home. Which just goes to show it's not just actors who play competent experts that have to deal with this.
 * William Shatner tells a tale of being on a tourist cruise when another tourist fell into the water and began drowning. Like any normal human being, he stood aside while professional help was obtained. So many people were staring at him, expecting him to act the hero that he eventually caved in to peer pressure and dived in after the struggling tourist. As any lifeguard will tell you, this is the worst thing you can do. Both Shatner and the original victim had to be rescued.
 * Another Shatner example: several pages on Priceline.com are written in first person in the voice of Shatner's "Priceline Negotiator" persona. The "terms and conditions" link at the bottom of the page is introduced with the text: "I'm not a lawyer (I played one on TV), but here is the legal information you need to know."
 * And yet another Shatner example, He was travelling in Nepal, riding a little mountain pony up a steep slope. His group came upon a little hut/tea house and the old dude running the teashop looked at Shatner and said "Captain Kirk?". Turned out he had an ancient black & white TV, run off a truck battery and Star Trek was one of his favourite programmes.
 * Most Soap Opera actors say that this happens to them so often that they've become used to just going along with it.
 * This trope is the measure Hispanic Soap Opera actors use to know how well they are doing in the role and how well the soap is going.
 * At the Star Trek 30th anniversary celebration, Joan Collins mentioned that whenever she was asked "Aren't you Alexis, that bitch from Dynasty?", she replied, "No, I'm Edith Keeler, Depression-era social worker from Star Trek the Original Series" ("The City On The Edge of Forever")
 * In one of the Buffy the Vampire Slayer DVD extras, James Marsters says "I'm not a vampire, but I play one on TV."
 * In the 1970's, James Garner and Mariette Hartley did a number of commercials for Polaroid cameras. The way they played against each other, one would get the impression they were in fact a domestic couple, though this was never stated in the commercials. Mariette Hartley took to wearing these lettered sweatshirts that read "I am not James Garner's wife". Her baby has a shirt that read "I am not James Garner's child".

 * Fiona Shaw and Richard Griffiths, (who played Aunt Petunia and Uncle Vernon, respectively, in the Harry Potter films) have noted that small children are sometimes scared when they see them. Shaw mentioned that one little boy was even reduced to tears.
 * Tom Felton (a.k.a. Draco Malfoy) has noted that when younger children meet him, they tend to be afraid: "We get a lot of kids down in the studios all the time and are very excited to meet Daniel, Rupert and Emma, and they get the handshakes and the hugs! I try to be as friendly as I can, but no matter how much I try they seem to hide behind their parents legs or cower behind some object. I don’t get a good rap from the children! I take it as a compliment, if they think I’m evil then I must be doing something right!" However, there was also a bizarre incident with a not-quite-so-young fan. An American man legally changed his name to "Lucius Malfoy" and sent Felton paperwork which would allow him to disown his parents and be adopted by "Lucius", whom had additionally named his house "Malfoy Manor".
 * Maggie Smith has apparently frequently explained to young children that she can't really turn into a cat.
 * Mark Williams (Arthur Weasley) "went out with the twins and Rupert, and we went out for a curry and a pint, that was hilarious. There were a load of teenagers with their phones, really polite, going, 'Can we take a picture of you?' to the guys. And one girl turned to me and said, 'And your dad.'"
 * Children used to come up to Tom Baker and ask him if he enjoyed travelling in time and could they come with him. (Apparently he used to play along with it rather than traumatize a young mind.)
 * He also has said in interviews that once in a while men would try to pick fights with him, to show they were tougher than The Doctor, and he would have to talk them out of it.
 * Dr Pepper has had some fun playing with this lately in a series of commercials where celebrities Neil Patrick Harris, Gene Simmons, and Julius Erving tell us that we can trust them, because they're doctors. That'd be Dr. Doogie Howser (played on TV), Dr. Love (popular song), and Dr. J (nickname), respectively.
 * Neil Patrick Harris also did this commercial for Old Spice, claiming he "used to be a doctor for pretend."

 * Smallville's Tom Welling intervened and fought off men attempting to mug a woman. When she saw who had saved her, she reportedly said, "Wow, you really are Superman." She was kidding, but she apparently wasn't that far off.
 * Star Trek: John de Lancie, the actor playing Q, said at one time that he was, more jokingly or more seriously, randomly asked by people on the street how is it to be an all powerful entity. Reportedly, he'd answer them "It's just a role".
 * OTOH he tells an anecdote about being confronted by a big tattooed biker type who he was ure was going to mug him, at the very least:
 * 'Biker': "You're Q right?"
 * John (deciding his chances of survival are greater if he pretends to be omnipotent):"Um ... Yeah"
 * "Biker': "So can you bring dead people back to life?"
 * John: "Only if I like them"
 * 'Biker' grunts and walks off and John thinks 'Trekkies come in all forms.'
 * Amy Adams told the story on a talk show about how a young girl recognized her as Giselle, and wondered why she was walking around as a regular person. Adams replied that she didn't want to draw attention to herself, and asked the girl not to tell anyone.
 * A similar story was told by Selena Gomez. A young fan came up to her and asked, "Alex? Is the magic real?" She asked him, "Do you believe it's real?" He replied, almost crying, "Yes, I do believe it's real." She smiled and said, "That's all that matters."
 * Franz Xaver Kroetz who played gossip reporter "Baby Schimmerlos" in the German series Kir Royal was asked by some newspapers to write columns for them and did so - despite the fact that he had no experience with this kind of writing and the result was... meager. Though Kroetz was an already a renowned playwright, they just overestimated his ability to write for them.
 * Liv Tyler reports this happening to her after the release of The Fellowship Of The Ring. "My husband and I were sleeping, and I woke to the sound of our friend's two little boys going around the bedrooms opening the doors and looking in. When they got to our door, one little boy went to open it and the other said, 'No! Don't open that door. The princess is sleeping in there.
 * In a weird reversed example, Star Trek's Grace Lee Whitney states in her autobiography that she sometime has difficulty differentiating reality and fantasy. For example, she recalls being disillusioned when she filmed an episode of The Western Bat Masterson and saw Gene Barry wincing in pain after stubbing his toe, despite the fact that any injury he sustained while in-character was Only a Flesh Wound. She also apparently tended to get so into roles that she started to forget it was fake. A therapist even told her that part of the reason she was so upset about being written out of Star Trek was because she had difficulty separating herself from Yeoman Rand.
 * Ed Westwick gets a lot of disappointment from fans when they realise he's not as dark and brooding as his Gossip Girl character. While he seems a bit tired of being mistaken for having the same faults as his character he has admitted that the line: "I'm Chuck Bass" usually works really well for him to pick up women.
 * Malcolm Jamal-Warner, who played Theo on The Cosby Show, wrote in his autobiography that half his fan mail was addressed to his character's name, and kids would frequently ask to be adopted into his family so they could appear on the show.

Live-Action TV
"O'Neill: No. But he plays one on TV."
 * Parodied in an episode of Stargate SG-1. A nervous villager points out that Teal'c is a Jaffa. O'Neill then replies in his typical fashion that...


 * On the Season One finale of Party Down, Roman harasses George Takei concerning his take on the Vulcan Mind-Meld - which, of course, was not Sulu's area of expertise.

Web Original
"Marik: Also joining us is celebrity voice actor Dan Green!
 * The Amazing Super Powers webcomic strip depicting a flight stewardess asking if there were any doctors onboard as the pilot had just had a heart attack.

Western Animation

 * An in-universe example: in Batman the Animated Series, a certain Simon Trent played a Batman-like superhero named Gray Ghost in an immensely popular TV show which little Bruce was a big fan of. In the episode "Beware of the Gray Ghost", set decades later, Trent is facing poverty partly because he cannot get any roles because everyone still thinks of him as the Gray Ghost. Then Batman comes along on a case and ropes him in to assist him. Much to his own surprise, Trent make a passable superhero (and more importantly, learns that the Big Badass Batman is primarily inspired by his portrayal of one).
 * A fairly meta example, when you consider the actor voicing Trent is none other than Adam West.
 * Series one of Monkey Dust had a sketch where the comedian David Baddiel would frequently be called on to perform difficult specialist tasks (such as brain surgery or piloting a space shuttle) because as a famous comedian he should be able to adapt to any role, even off-stage.
