Actor Jim Caviezel's body has taken a beating as a result of his work on hit Tv show Person Of Interest - he has suffered a separated shoulder and a cracked rib.

The 44 year old is often involved in hand-to-hand combat stunt scenes in his role as a former Cia agent in the U.S. crime series, and the actor admits all the action is starting to take a toll on his body.

He tells People magazine, "It's hard when you get a cracked rib... (I've had) a separated shoulder, a busted nose, a kneecap here and there and (a) punch to the face... The injuries do come in handy because (the writers) just work it in. Viewers will think, 'Great makeup work.' Oh, yeah, it's great (because it's real)."
