Kiefer Sutherland: (on the demanding work hours for 24) Yeah. I ran into Matthew Perry recently and he was teasing me - we used to play hockey together, so we're old pals. On Friends, they work like four days a week - half days at that. He was joking about my schedule, which is 10 months a year opposed to the standard 8, and we shoot for 12 to 14 hours a day, 5 days a week, plus prep work on the weekends. Towards the end of last year, we were into hard nights: 5 P.M. until 5 A.M.
