Real easy… think 6 degrees of Kevin whats-his-name
Someone says the name of a movie. The next person must state the name of someone who starred (or appear in the credits) in that movie.
(example: Person 1. Rocky.
Person 2. Sylvester Stallone.
Person 1: Cliffhanger.
Person 2: John Lithgow (who was in Cliffhanger with Stallone)
Person 1: Harry and the Hendersons (starring John Lithgow)
I shall start with a movie: (first round)
IF NO ONE HAS RESPONDED (IN AT LEAST OVER AN HOUR) ANNOUNCE THE LAST PERSON AS WINNER AND RESTART A NEW ROUND WITH A NEW MOVIE TITLE.
