Let the Academy of Motion Picture Arts and Sciences and all of those film festivals hand out trophies for movies offering high drama and art. The folks who vote for the MTV Movie Awards appeared to have fun as their top criteria when they handed out their golden popcorn trophy Sunday night. They gave Transformers their top award for best film. Johnnie Depp accepted trophies for best comedic performance for Pirates of the Caribbean: At World's End and for best villain for Sweeney Todd. Accepting the first award, Depp seemed as curious about it as anyone in the audience. "You can ask anybody," he said. "I'm not a very funny person. I'm not even remotely funny."
