Saw 3D's Costas Mandylor has revealed he entertained himself during the horror movie's long shoot by 'torturing' his trapped co-stars.
The actor, who reprises his role as the Jigsaw Killer's successor Mark Hoffman, said while promoting the film in Hollywood: "I make fun of a lot of the people that are actually in the traps for two or three days."
He laughed: "They can't do anything to me, so I'll go up and slap them in the head and make fun of them. They want to kill me but they can't!"
The actor promised fans won't be disappointed when the seventh and final movie comes out this Friday.
"I heard if anybody is a little bit squeamish they better get ready for this one," he teased. "I'm a really bad boy and it's going to be very obvious that I do something really terrible to somebody, well actually to a lot of people, but for one in particular I think girls are going to be very upset with me."
