Gerard Butler

Yes, we’re having trouble knowing who’s Gerard Butler and who’s not Gerard Butler in the picture. But that’s simply a sign that his stunt double—the uber-experienced Airon Armstrong—is the right man for the job. He made (and continues to make) stunts in more than 100 productions, some of which were alongside Butler.

An action-movie actor first and foremost, Butler has most recently starred in “Last Seen Alive.” He spent months training for his fighting scenes in the epic “300,” but he was denied the opportunity to perform most of his dangerous scenes in the movie—something that reportedly left him very frustrated.
