David Gregory (ex-Ford, OLTL) will be featured on NBC'S CONSTANTINE tonight as Eddie, who will be an integral part of the episode. "It's going to be a wild ride," the actor tells Digest. "No one is who you think they are! Let's just say I get knocked around a lot." Gregory says he received high praise from his stunt double. "The stuntman said I was the toughest actor he's ever met. I'll take it!" CONSTANTINE airs at 10 p.m ET/PT.
