Zodiac (webcomic)/Trivia

The film contains these examples, which have been deemed to be Trivia:

 * Hey, It's That Guy!: Would you belive Bob Vaughn is actually the voice of Roger Rabbit?!
 * John Getz as Templeton Peck who you'll see again in Fincher's The Social Network
 * Casey Jones (Elias Koteas)
 * Sean Finnerty (Donal Logue)
 * The Other Darrin / The Other Marty: Intentionally done with the Zodiac killer being played by different actors through the film to match what eyewitnesses said.
 * Role Association: A retroactive case. Now that Robert Downey Jr. and Mark Ruffalo are Iron Man and the Hulk in The Avengers, respectively, fans have had lots of fun digging up this movie.
