Keifer Sutherland & Freddie Prinze Jr.

Freddie Prinze Jr. has been very vocal about his negative experience working alongside Kiefer Sutherland on 24. “I did 24; it was terrible. I hated every moment of it,” Prinze Jr. said. “Kiefer was the most unprofessional dude in the world. That’s not me talking trash; I’d say it to his face.
