Actor and filmmaker Mel Gibson, director of the new film 'Apocalypto', smiles before receiving the Chairman's Visionary Award at the 2006 Latino Global Business Conference and Digital Expo in Beverly Hills, California, November 2, 2006.

George Clooney might be hot, but Mel Gibson is freezing, according to a list of Hollywood's 'coldest' celebrities published by a movie website.

While Clooney was named "Sexiest Man Alive" for 2006 by People magazine last week, Gibson had to content himself with topping Filmthreat.com's 'Frigid 50' list of movie stars who are out of fashion.
