I gotta stand up for Vince here. He doesn't always make gold but I enjoy the hell out of some of his movies and Rockford Files was great( i own most of the seasons). Jim Rockford wasn't a pretty boy who always come out bright and shiny. He was rough around the edges with a dry sense of humor and walked away with more bruises than anything. Vaughn can play that with ease. Vince seems to be only remembered for his comedic performances when there is more to him than that.

A cool Dry Place
Return to Paradise

Vaughn is a good actor, people jus seem to forget that.

He has a good look for the role also. Garner was a big guy too. Vince jus needs to drop a few pounds...he has put some weight on
