Freddie Prinze Jr. Calls Kiefer Sutherland 'Most Unprofessional Dude in the World'

Freddie Prinze, Jr. is opening up about his experience working on 24 as a guest star back in 2010, a job that almost made him quit acting.

“I did 24, it was terrible. I hated every moment of it,” Freddie told ABC News. “Kiefer [Sutherland] 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.”

“I went and worked for Vince McMahon at the WWE for Christ’s sake and it was a crazier job than working with Kiefer,” he added. “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.”
