Saw It in a Movie Once

A group of characters is in some sort of fix or trouble. One character steps up and:


 * contrives a plan just Crazy Enough to Work
 * or manages a bit of out of character or unexpected Bad Assery
 * or pulls off a clever bit of dialogue that stops everyone in their tracks
 * pulls off some manner of complicated stunt like an old pro

The other people in the scenario, Mooks, Distressed Damsel, and even the villain are impressed by this display of incredible competence and showmanship.

The character who just amazed the crowd shrugs it off modestly, saying simply, "Saw it in a movie once."

Variations include:
 * Saw it on a TV show
 * Read it in a book
 * My dad/mentor/grandfather once told me a story about it
 * Dreamed I did it

Sister trope to both Taught by Television and I Know Mortal Kombat. See also Crouching Moron, Hidden Badass.

Anime

 * Full Metal Panic: Kaname says this in the first season when she, Sousuke, and Kurz are trapped by an army of soldiers in a small trench. The movie she remembers? Butch Cassidy and the Sundance Kid. Yeah, not too encouraging. They come out alright, though.
 * The World God Only Knows: This is Dating Sim Otaku Keima Katsuragi's schtick. Whenever someone asks him how he could make a bizarre leap of logic or figure out something in an instant, he replies, "It often goes like this. In games."

Film
"Harry Dunn: That was genius, Lloyd ... sheer genius. Where did you come up with a scam like that?
 * Demolition Man: Lenina (Sandra Bullock) explained away her martial arts prowess as being from watching Jackie Chan movies.
 * In The Red Green Show movie, Duct Tape Forever, Harold tries to stop the men after him and Red by dumping gasoline on the road to slip up the limo behind them. The reasoning? He saw it in a James Bond movie once. It works...kind of...just not the way you'd expect.
 * Subverted in Dumb and Dumber when Lloyd (Jim Carrey) tricks a group of tough guys they encountered in a restaurant to pay for a meal for himself and Harry (Jeff Daniels), claiming he saw it in a movie. However, it turns out the plan wasn't as foolproof as they thought.

Lloyd Christmas: I saw it in a movie once.

Harry Dunn: Ha ha! That was incredible! So what happened? So the guy tricked some sucker into picking up his tab and gets away with it scot free?

Lloyd Christmas: No, in the movie they catch up to him a half a mile down the road and slit his throat. It was a good one."

"Mikey: I saw this on the Hardy Boys once. We lead a trail of jewels into one cave, and then hide out in another, and when the Fratelli's go into that cave, then we can make a run for it."
 * The Goonies: Mikey suggests a plan to escape from the pursuing villains in based on a Hardy Boys story.

"Murdock: (While flying a helicopter) Hold on, guys, I'm gonna try something I saw in a cartoon once!"
 * The a Team:

""I know this is gonna sound crazy, but in this one film I starred in we had to infiltrate the girl's bathroom of a highschool. So we built a catapult out of women's underwear and launched ourselves over the fence!"
 * Hilariously played with in Tropic Thunder by one of the protagnoists, an actor, slowly going insane from withdrawal symptoms (due to being a junkie)

(Everyone stares at him for a moment before trying to find a more reasonable plan)"

"Frank: It worked in the movie!
 * In Return of the Living Dead, the Genre Savvy characters who have seen Night of the Living Dead try to put a zombie down by Removing the Head or Destroying the Brain, with less than satisfactory results.

Burt:Well, it ain't working now, Frank!

Freddy: You mean the movie lied?"

Literature

 * Parodied in The Adventures of Huckleberry Finn. When Tom shows up to help Huck break Jim out of captivity, Huck's pragmatic plans are always dismissed by Tom, because they 'ain't got enough style' and Tom likes to do things that he got out of books, like trying to dig a tunnel with case knives or giving Jim a bunch of pet snakes and rats.
 * The Golden Rendezvous by Alistair MacLean. The protagonist disarms the Big Bad, who has a concealed shoulder holster, simply by yanking his jacket down over his shoulders, immobilising his arms. When the Big Bad calmly asks if the protagonist is a professional like himself, he replies "American movies."
 * In Infinity Beach, Solly gets the idea of blowing the alien Shroud out of Hammersmith's airlock from a movie (implied to be Alien). Unlike in Alien, it doesn't work.
 * In the Hoka stories, by Poul Anderson and Gordon R. Dickson, the Hokas--a race of teddy-bear-like aliens--operate entirely on this principle. They absorb fictive universes (essentially, the race is a sponge for tropes), and become them. Cowboys, spacemen, Sherlock Holmes, The Jungle Book--they cover a lot of ground.

Live Action TV
"Cuddy: Is this your master plan? Disrupt hospital business until I replace your carpet?
 * House parodies this in a third season episode "Lines in the Sand" when he conducts a differential in the lobby:

House: Devious. Saw it in a James Bond movie."

"Robber: Where'd you learn to drive like that?
 * Abed, in Community, occasionally bursts out with this trope.
 * Psych episode "Romeo and Juliet and Juliet" has Shawn mention "I saw this in a Jackie Chan movie..."
 * The A-Team Season 3 episode "Breakout" has a couple of robbers coercing Murdock at gun point to drive the van to get away. Murdock, normally an Ace Pilot, breaks out some Badass Driver skills:

Murdock (deadpan): I saw Cannonball Run five times."


 * Heroes: Used very literally with Monica, whose superpower is being able to copy anything she's seen in person or on TV - carve a tomato into a rose, play the piano, kick a robber's ass with a flashy wrestling move, Ceiling Cling...
 * Garak on Star Trek: Deep Space Nine often uses variations of this phrase to handwave his impressive abilities or intimate knowledge of things like classified military codes. Since almost everyone knows he used to be an actual spy (and a fairly important one at that), none of the main cast believe his explanations for a second.
 * Quoth Castle, as he's about to do something stupid while being held hostage at a bank robbery: "don't worry mother, I saw this work on Die Hard."
 * Tony in NCIS is an inveterate film buff. When he comes up with a scheme to override a video feed in order to end a hostage situation, his colleagues automatically assume he saw it in a movie, and in spite of his protests they ultimately pinpoint which movie (it was Speed).
 * Blossom: Blossom blinds an intruder (who turns out to actually be her brother) by blowing talcum powder in face. When Six asks her where she learned that trick, Blossom replies "MacGyver". (Also counts as an Actor Allusion as as Blossom's actress Mayim Bialik had played a recurring character on MacGyver.

Newspaper Comics

 * FoxTrot: After Jason and Paige spill cola into Andy's computer, Piage urges Jason to fix it. He says he remembers seeing MacGyver do something similar. They need to prise the computer open, clean it out... and then hook it up to bicycle. Or maybe it was a minivan.

Stand Up Comedy

 * Steven Wright, to a hitchhiker he'd picked up: "Put your seatbelt on, I want to try something. I saw it in a cartoon once, but I'm pretty sure I can do it."

Video Games

 * Subverted in CROSS†CHANNEL. In two different scenes, Taichi insists he can drive cars because he's seen how it works in manga. Naturally, this leads to hilarious results.
 * Played straight but justified in Umineko no Naku Koro ni. Trying to interpret the game board's story as a mystery rather than a fantasy story, various characters use knowledge gained from reading mystery novels.
 * Chuck Greene from Dead Rising can learn new combo weapons by, among other things, looking at movie posters. Namely movies by Clint Rockfoot.

Web Comics

 * Least I Could Do has Rayne bust out a Big No at goofing a chance with a girl. She calls him on being a bit dramatic and he says he Saw It in a Movie Once.
 * Cyanide and Happiness got that guy with a cat, and he did read this comic...
 * In The Inexplicable Adventures of Bob many of Molly's engineering feats are inspired by pop culture. When she activated her transforming snow ballista, she managed to include shout outs to Tom Corbett: Space Cadet, Robotech, Battle of the Planets, Sailor Moon, and Ultraman.

 * From the same series: Michelangelo and Donatello were tied up back to-back in chairs with a bomb next to them. Mikey revealed that he had seen a scene like this before on TV and, following his direction, the two rocked back and forth to tip over onto the floor. However, when Donatello asked what to do next, Mikey realized that he didn't know--at the time, he'd gone to get popcorn before the scene had finished.
