This game can be as simple or as difficult as you like, the initial post will be the title of a movie and the response will be any actor in the movie and another movie they were in, and the following answer will be another actor in the new movie named and a different movie they were in!
for egsample:
I'd post SNATCH
answer JASON STATHAM
THE ITALIAN JOB
next answer CHARLIZE THERON
HANCOCK
The more unknown the movie, the more difficult the game becomes, so try to keep it mainstream(or don't)!
So here's the first movie
OCEANS ELEVEN
