Released in 1926, The General is one of the very first blockbuster action comedies. Buster Keaton’s boundless energy is on full display in this real-life story of a Confederate soldier who must single-handedly rescue a train from a team of Union hijackers. In crude modern Hollywood pitch parlance, it’s Die Hard on a train, only with more slapstick and a brilliant lead actor who does all his own stunts. Pretty much every action film you’ve ever seen borrows beats from The General—or, more likely, they steal from films that stole fromThe General. With live organ accompaniment.
