Freddie Prinze Jr. is done being polite about Kiefer Sutherland's antics

Ever wonder why we stopped seeing so much of Freddie Prinze Jr.? It turns out his 2010 guest stint on 24 was so painful, he almost quit the biz. Instead of doing the usual, "I needed a break," or "It wasn't the most creatively satisfying experience," Prinze got real with ABC News, calling out how horrid his experience was working alongside 24 star Kiefer Sutherland.

“I did 24, it was terrible. I hated every moment of it,” the actor told ABC News. "Kiefer was the most unprofessional dude in the world. That’s not me talking trash, I’d say it to his face, I think everyone that’s worked with him has said that. … I just wanted to quit the business after that. So, I just sort of stopped.”

Freddie hit up Comic-Con to promote his new Disney X D series Star Wars Rebels. Guess who else was there? Kiefer, promoting 24: Live Another Day. No matter, at least for this interview.

“I went and worked for Vince McMahon at the WWE for Christ’s sake and it was a crazier job than working with Kiefer,” added Prinze. “But, at least he was cool and tall. I didn’t have to take my shoes off to do scenes with him, which they made me do. Just put the guy on an apple box or don’t hire me next time. You know I’m 6 feet and he’s 5’4.”
