The Goat by Buster Keaton

The Goat is a 1921 American two-reel silent comedy film written, and co-directed by Malcolm St. Clair and Buster Keaton and starring Keaton.

The comic premise for The Goat emerges as a series of mistaken identities in which Keaton is the visual double of a murderer who is pursued by a posse. Keaton’s love interest is the daughter of the policeman who is leading the manhunt.

This short contains one of Keaton's more memorable images: a distant, speeding train approaches the camera, and stops with a close-up of Keaton who has been sitting on the front of the locomotive's cowcatcher.

Dumb luck sets some policemen on his trail -- after a series of innovative escapes, he gets mistaken for a murderer with a price on his head, which means the people that aren't chasing him are fleeing from him.
