What It’s About: When the men of the battleship Ptoemkin are served rancid meat, the resulting protest, and treatment of the protesters by the ship’s officers leads to mutiny, and uprising in Odessa, and the brutal suppression of both by Tsarist forces.
Why Watch it Today?: The real mutiny began today in 1905. Battleship Ptoemkin was ground breaking Soviet director Sergei Eisenstein’s second (and even better known) feature film after Strike, one of the greatest and most influential silent films.

The League of Dead Films 
Still a classic. I had to point out to someone a few years back that the scene in The Untouchables he liked so much was cribbed from this film, but the original was MUCH more compelling. He didn’t agree until I made him sit through the film on a bet and yup, he lost (and got knocked back in his seat at that Odessa Steps scene)…
Yeah, you can’t compete with that scene for impact.
