The rules to this are different, it's based on a drinking game I know.
The first person puts up the name of someone famous, the next person names a film they were in, the person after that names someone else from that film and then the next puts up the name of a film they were in.
So If I put up Harrison Ford, the next person could put up Raiders of the Lost Ark, that gives us Denholm Elliott which gives us The Cruel Sea.
I'll start:
Harrison Ford.
