The actor was shooting an underwater scene when he had to take a trip to the emergency room after slicing open his hand.
He tells Entertainment Weekly magazine doctors were advised not to stitch up the wound for fear of infection – and so they decided to glue over the deep cut.
Kim tells the publication, “I actually ripped open my hand on a stray drywall screw that was underwater. I had to run to the hospital to get my hand glued up. They were going to stitch it up, but they decided against it because they thought I might have to go back in the water again and they were worrying about infection. So they ended up gluing it, so it was a more watertight seal.
“People are asking me if I’m going to take any souvenir from the show, but I don’t need a piece of the show; it’s taken a piece of me! I will have this scar as a souvenir.”
