Cambist Films (1973)
A plague film that was decades ahead of its time is half a century old today. The Crazies was written and directed by George A. Romero and premiered in theaters on March 16th, 1973.
The Crazies wasn't a hit at the box office, but it found its audience on home video in the 80's and 90's, which is where I experienced it for the first time. It got a remake in 2010, and it's one of the few times that I've enjoyed the new version as much as the original, but both films are definitely worth watching.
