This is a game I used to play on another forum. The way it works is this: One person posts the title of a movie and the name of an actor/actress that appeared in the movie (does not have to be the lead, supporting cast or even minor role in fine). Then the next person posts another movie that person appeared in, then name another cast member for that same movie. For example:
Post 1: In Hancock, Will Smith
Post 2: Will Smith in Independence Day. In Independence Day, Jeff Goldblum.
Post 3: Jeff Goldblum in Jurassic Park. In Jurassic Park, Sam Niell.
And so on. And of course it goes without saying that it's no fair posting an actor or actress that has never appeared in any other movies (not that there are very many of those).
And try to keep this in movies, TV shows do NOT count.
I will start with:
In The Princess Bride, Cary Elwes.
