According to Moviehole, not only are the rumors about Vin Diesel playing the Silver Surfer in the second Fantastic Four movie untrue, but the Surfer won't even be played by a human, with director Tim Story opting for an all CGI design.
The film's director, Tim Story, told me this morning that although The Silver Surfer is indeed in the movie, it won't be Vin Diesel playing him.
"No truth to it", Story said, when asked about the Diesel rumours. "The Surfer will be a new CGI design being developed especially for the movie. It's going to be incredible."
The CGI system being developed to make a man appear to be made of silver is so sophisticated, it's being codenamed, "The same crap they did for T-1000 in Terminator 2." At least by me.
As a condolence to Vin, I'd like to point out that it's probably only going to help your career to not to play a silver alien that rides on a surfboard. Yes, it worked for Brando, but he's Brando.
