We start off by naming a movie and then naming an actor/actress who starred in that movie. The next person will continue the chain by restating that actor/actress and then name a different movie that they appeared in. The next player will restate the movie from the previous post and list a different actor/actress, and so on.
If we get to a dead end, meaning we hit a point where a person names a "one hit wonder" type of actor/actress or film that prevents us from continuing the game, then the next person who wants to post and sees this problem, can pick a new film & star of their choice...just make sure to state in capitals "NEW MOVIE" before your entry.
If there are two movies out there with the same title (sometimes a remake of an old one) put the date of approximate release so we know which one you're referring to.
A good site to refer to if you get stuck is:
