Katee Sackhoff

Sorry Battlestar Galactica fans, Katee Sackhoff isn't arriving at the New York CTU in a raptor and she's definitely not Starbuck anymore. Sackhoff joins 24 as Dana Walsh, a computer analyst who has a background she's trying to keep hidden.

How does Dana stand apart from Starbuck? "Dana is very different," Sackhoff told TVGuide.com on the set of 24. "She's very calculated, she's very smart. She's very capable.

"When Starbuck didn't like something, she just shot 'em. When Dana doesn't like something, she has to reprogram the computer."
