The Great Train Robbery/YMMV


 * Adaptation Displacement: It was based on a stage play.
 * Older Than They Think: Despite its reputation, it isn't the first filmed Western -- IMDb has entries for at least three earlier examples.
 * Special Effects Failure: Averted; while it's very obviously a dummy being thrown off the train, the movie is so old that this was one of the first (if not the first) special effects ever used in film.
