This game is simple. Simply link to a movie from the previous one through an actor/actress that was in both.
For instance, Person A posts Terminator 2, Person B then posts "True Lies via Arnold Schwarzenegger", and Person C has to link from True Lies to another movie with an actor/actress that was in both. Round will continue until either nobody can link to another movie (time limit is 3 days after last post) or until a movie or actor is repeated, then the new round will start.
Only rules are no porno movies, and no anime or other hard to link to movies.
Let's start with Airplane!
