I happened upon this little gem when I was wandering through a used record/movie shop. For only one dollar, I figured I'd give it a shot.
The film follows the same idea presented in 1982's Creepshow, persented three horror stories from different directors (tied together by the plot of the narrator).
The film is most remembered for having a short directed by Night of the Living Dead creator George A. Romero, based on a story by Stephen King. Unfortunately, this tale was the least impressive of the three, but still fun.
The stories include Lot 249, in which Steve Buscemi uses a mummy to take revenge on those who wronged him; Cat From Hell, the aforementioned Romero/King tale, is just that: an evil cat that kills people; and Lover's Vow tells an unconventional tale concerning an artist, a gargoyle, and a promise that means life or death for the main character.
With special effects by KNB (those folks who started out with Evil Dead 2 and are now possibly the biggest gore-folk in Hollywood, Tales from the Darkside: The Movie is a fun, cheap buy if you ever come across it.
