The most nail-biting dramas often have the funniest sets. When long days are filled with take after take of someone dying on the operating table, downtime naturally becomes prank time.
So when I visited the 'Off the Map' set on a particularly busy day -- shooting a scene of the surgical aftermath of a hang-gliding accident, which you'll see at the end of the season -- I wasn't surprised to find the cast giggly, playful and ready to have fun between shots.
But who's the king of the jokes? The funniest when the cameras stop rolling? There's no doubt that man is 'Friday Night Lights' alum Zach Gilford. And as I learned in not one but three of my other cast interviews, he doesn't always wait for the cameras to stop before popping in with some goofball antics.
