We call it "The Movie Game" but, basically, you get all your friends together and sit around the room in a generally circular pattern. Someone starts by either naming a movie or an actor/actress. Then the next person, either clockwise or counter clockwise, which ever direction you want to go, chooses an actor from the named movie or a movie the named actor was in. This continues to alternate until the person can't name a movie/actor or is proven wrong. (It's sometimes good to have one person act as fact-checker). If you can't name something or someone, you're out. Last person in wins.

It's a good way to have some laughs while just hanging out getting high/drunk.

EDIT: Left out a step.
