17. 24 (what else?)
And the remix:
I believe President Logan, Cheng Zhi and Mandy are the only villains to survive three seasons and remain alive.
FAVORITE TORTURE SCENE
Kiefer Sutherland: "There was one I loved [in Season 5] where I was trying to get information from Peter Weller [who played Christopher Henderson], so I tortured his wife, JoBeth Williams. I was such a fan of those two actors, and she was so game for me shooting her in the knee."
FAVORITE DEATH SCENE
Kiefer: "Ryan Chappelle." [source]
Ah yes… The one where Chappelle dies one of 24's best (and most shocking and controversial) episodes, which President Bush unceremoniously bumped to hold a prime time press conference on Iraq and the war on terror.
Re-scheduled for the following Sunday, it garnered the lowest ratings of any episode of 24 through its first six seasons.
