6. Eliza Dushku -- Combine a hot girl with a part where she kicks some evildoer ass and you've basically got the Nielsen ratings on lockdown. The "Dollhouse" star has pretty much had the same butt-kicking hot chick role since her days on "Angel," "Buffy," and "Tru Calling." This role has an expiration date, Eliza, so we'd advise you to sign on for a Victorian-era tragic romance ASAP. There can still be some vampires you can stake, don't worry.
