Most awkward day on set: Ludwig, who plays one of the most brutal tributes, turned out to be a bit too good at hand-to-hand combat. “I was doing a fight scene, and I accidentally hit a stunt guy across the face with a bat,” he recalls. “He was bleeding everywhere. I thought they’d kill me if I didn’t keep going, so once they said, ‘Cut,’ I ran over and was like, ‘Dude, I’m so sorry!'”
Played by: Jacqueline Emerson
