Freddie Prinze Jr. had few positive things to say about his experience working on season 8 of 24 – specifically working with series star Kiefer Sutherland.

Freddie Prinze Jr. Slams Kiefer Sutherland

Prinze, 38, appeared at Comic-Con to promote his new Disney XD series Star Wars Rebels when he launched into an explanation about why he hasn’t been around much on the small or big screen lately. Prinze admitted that his absence can largely be attributed to his “terrible” time filming 24.

"I did 24 … it was terrible. I hated every moment of it,” Prinze told ABC News. “I just wanted to quit the business after that. So, I just sort of stopped."

"Kiefer was the most unprofessional dude in the world,” Prinze explained. “That's not me talking trash, I'd say it to his face. I think everyone that's worked with him has said that."

In addition to Kiefer’s unprofessional attitude, Prinze also took issue with the accommodations that were made for the actor’s height.

"I went and worked for Vince McMahon at the WWE, for Christ's sake and it was a crazier job than working with Kiefer," Prinze said, adding, “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 [at 24]. 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''."

In recent years, Prinze has made guest appearances on Witches of East End and, most recently, on Fox’s Bones.
