Matt Damon, humanitarian? Sure, he'll toss his hat in the ring for any cause of George Clooney's, but what about Matt Damon, the man who's saving one life at a time? He's there, kids, for anyone who will listen — like The Good Shepard co-star Mark Ivanir.

In one scene, Ivanir, who plays a KGB officer, is tortured by three CIA agents who cut off his clothes with scissors, hold him down, put a burlap bag over his head and douse his naked body with freezing water.

“Matt told me, ‘We should have a warning sign if you feel like you’re really in danger. You really could get hurt with that mask suffocating your face,'” Ivanir tells Us.

“Sure enough, if Matt hadn’t thought of an alert to stop filming, I really would have passed out and died. It would have been great publicity for the film, but not so good for my career!”

We also have a warning sign: When we say "Kentucky." That's when we expect our partner to remove the clothespins from our nipples, the fishing wire from our scrotum, the hot wax from our chest, and the gerbil from our ass. Works like a charm, everytime.
