And now the equivalent of crack for a movie buff:
 

May I introduce you to www.hsx.com

Hollywood Stock exchange is a fantasy securities market where movies are stocks and actors are bonds. It has all the sophistication of a real market incluing shorting, covering, limit orders and options. Hundreds of thousands of traders participate. Phenominal amounts of time have been wasted around my office in the last five months since one of my friends turned me onto it.

Be sure to read all the "help" information to get the most out of it (ie, there is a method to success and it has little to do with who you happen to like).

Enjoy.
