YMMV / The Great Train Robbery (1903)

• Adaptation Displacement: It is based on a stage play, which is no longer performed and was never filmed in its original form. Therefore, most present day people who've seen it don't know that it's an adaptation.
• Big-Lipped Alligator Moment: Even with how iconic the shot is and how much it's been parodied, the scene where the Bandit Leader shoots at the camera in the end, still has no relevance to the plot.
• Memetic Mutation: The ending shot where Justus D. Barnes shoots at the camera has been referenced and parodied to death.
• 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: For modern viewers it's very obvious that the guy thrown off the train is actually a dummy. At the time, however, special effects like this were novel and convincing. Even now it qualifies for a Grandfather Clause.
• Unintentional Period Piece: This was made in 1903, which means it was made during the Wild West era. Actual train robberies as depicted in the film were happening during that time period.
