Bad casting decisions you'd love to see
 

Hulk Hogan as the next Terminator. That would be epic.

Will Smith as Chuck Norris in a movie based around random Chuck Norris facts. It'd be worth it just for the beard.

Shia LeBouf as Indiana Jones' son.

Wait...

Will Smith as Samuel L Jackson in a movie about Samuel L Jackson playing the part of Chuck Norris.

Keanu Reeves and Tom Cruise in a cliched 80s style cop buddy action movie. The most wooden actor in hollywood coupled with the most bat shit insane actor in hollywood, what could possibly go wrong?!!

Rick Moranis as Doctor Who.

Suggested Movie Title: Norris: The Chuck Norris Chuck Norris Norris The Musical Chuck Norris

Speaking of musicals: Keanu Reeves in a musical. Period.

Leonardo De Caprio as Shaft. I'd love to see a movie that horrible...

Joel Schumacher directing back to The Future VI starring Shia LeBouf as Jules Brown in a CRRAAaazzzY adventure through time!

Arnold Schwarzenegger and Arnold Schwarzenegger as Balinbo and Jorgun in a live action Gurren Lagann.

I've always had this odd fantasy about a movie starring Stalone, Schwarzenegger, Van Damme VS Jackie Chan, Jet Li, and (the ghost of Bruce Lee) in a really crappy action film sort of along the lines of Tropic Thunder.
