Laura Harris has the look of an angel and a knack for devilish roles. Remember The Faculty? That was Harris as the teen-killing alien. And 24's good girl gone bad — the one who tried to nuke Los Angeles? Yep, that was Harris, too. These days, the 26-year-old Canadian transplant to L.A. shines as a sex-obsessed grim reaper on Dead Like Me, Showtime's odd new dramedy (Fridays at 10 pm/ET). Welcome to her dark side.

TV Guide Online: What's up with you and these sinister parts?
Harris:
I think [casting agents] love the surprise factor. Whenever I read for parts, they bring in all these blond, innocent-looking creatures. Then they ask us to be evil.

TVGO: So you're a good bad girl?
Harris:
I guess so.

TVGO: What's the last law you broke?
Harris:
(Long pause) I guess I am a speed demon and a fierce jaywalker. And sometimes, I take fruit salads over the border.

TVGO: As an actress, what's the most interesting way you've learned to kill people?
Harris:
For 24, I had to learn to use a gun. That's the first I've ever held one. It was too big for my hands. And I was sweating so much that it kept slipping. Now, I'm waiting for that kung fu movie where I can kick butt Charlie's Angels-style.

TVGO: Speaking of bad kharma, fans of 24 hated your character, Marie Warner, after she shot her fiancé and tried to nuke L.A. Did you have to hire a bodyguard to go to the mall?
Harris:
No. Thank goodness. That's when looking innocent came in handy. I did get a lot of muttered comments like, "Oh, I hate you!" But then I'd turn around, and they'd correct themselves.

TVGO: Will the evil Ms. Warner return to 24?
Harris:
Well, I'm not dead. And if you're not dead, there's the potential to come back. And that's all I'm at liberty to say.

TVGO: Now that you're on Dead Like Me, have you thought about your own demise?
Harris:
Well, I'm 26 now. And we're in a time where I could potentially live to be 140. So I'm taking vitamins and doing crossword puzzles to make sure I don't get Alzheimer's. I'm trying to ensure that I make it that far.
