If you remember the movie name game, you remember the rules, but here they are for newcomers.
1. Someone names a movie.
2. Someone else names an actor in that movie.
3. Someone else name a movie that actor from 2 was in.
4. Repeat number 2, then 3...so on.
Example -
Person 1. Kill Bill
Person 2. Uma Thurman.
Person 3. Pulp Fiction
Person 4. John Travolta
..etc etc.
So, to get things rolling...
War of the Worlds.
