Dennis Haysbert (President David Palmer)
For five seasons, we watched Dennis Haysbert play the respected President David Palmer and then of course, get assassinated in order to cover up a conspiracy in the American government. Many know he went on to play Nelson Mandela in the film The Color of Freedom. Then, Haysbert played Jonas Blane on the show The Unit. In addition, he’s voiced for Kung Fu Panda 2 and Wreck-It Ralph. For a short time, he worked on FOX’s Backstrom with Rainn Wilson. More recently, he got the roles of Julian Morse on Incorporated on Syfy and as Charlie Ventana on Reverie.
Mary Lynn Rajskub (Chloe O’Brian)
Next, we have one of Jack Bauer’s most trusted friends, Chloe O’Brian. After 24, Mary Lynn Rajskub’s career has sky-rocketed. Of course, we got to see Chloe O’Brian for 24: Live Another Day. You can see her in hit shows like Royal Pains, Grey’s Anatomy, New Girl, Arrested Development, 2 Broke Girls, Californication and It’s Always Sunny In Philadelphia. She plays Genevieve Mirren-Carter on FOX’s Brooklyn Nine-Nine with Andy Samberg.
