But one thing he probably didn't have in mind when signing on was stabbing a stunt actor—almost fatally—with a real knife while shooting a scene.

Contact Music reports that Smits was to stab action man Jeff Chase with a prop knife, but accidentally grabbed a real blade.

"For the scene, I was bound in Saran Wrap, duct tape over my mouth. I couldn't say a thing as I saw Jimmy grab at the knife," recounts Chase. "He picked up the real one by pure mistake. It was a mean looking knife."

Dexter lead actor Michael C. Hall caught what was about to happen and apparently yelled for Smits to stop, but it was too late, says Chase.

"I felt the thud in my chest... I had a piece of acrylic clear plastic about the size of a Post-it note over my heart... In eight out of 10 takes with the prop knife, Jimmy had missed the plastic. But by a miracle, an act of God, the knife landed at the very edge of the plastic."

Accidents on the set seem to be running rampant in Hollywood lately. But thankfully Jeff survived.
