Mel Gibson acting crazy on ‘Darkness’ set?

Well, sort of. Mel Gibson has been spotted on the set of Martin Campbell’s upcoming thriller “Edge of Darkness,” and somehow, he looks totally insane in most of the pics posted over at The Bag and Ugly.

For a little preview of Mel’s weird facial expressions, see above. Is he just goofing off? Anyway, Gibson stars as a homicide detective who discovers his daughter’s (Bojana Novakovic) secret life after she’s murdered on the steps of his house.

Also starring are Ray Winstone, Danny Huston, Shawn Roberts and Bojana Novakovic. William Monahan and Andrew Bovel wrote the script.
