My favorite cult classic movie memory is from the 1980's. It was one of those B-movies they show on HBO or Cinemax late at night. Its a Quest movie. Swords and Sorcery. Possibly apocalyptic scenario. Lots of scantily clad babes. Lots of macho dudes. They assembled a team to go on a quest for some reason. Dont remember what.
The best scene is when they try to cross a bridge. There is a guy standing there who won't let them pass. So one of our heroes takes his sword and chops the guys arm off. While we're distracted, the arm becomes a clone of the man guarding the bridge. Awesome movie. Probably cheeseball. Might be British but its def not Monty Python.
