Freddie Prinze Jr. had such an awful experience acting opposite Kiefer Sutherland in 24 that he "wanted to quit the business," he said. The actor explained to ABC News that working with Sutherland was "terrible." "I did 24, and it was terrible. I hated every moment of it," Prinze said. "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."
