'Battlestar Galactica's Tricia Helfer
The rebooted series garnered critical acclaim thanks to its terrific writing, deeply developed characters (give it up for Katee Sackhoff's hard-living, hard-drinking pilot Starbuck!), and themes and conflicts that resonated with the post 9/11 era regardless of the space-opera trappings. But let's just say you weren't likely to find posters of the ships in a fanboy's high-school locker; that space would be reserved for the show's main Cylon bombshell Tricia Helfer. Even among a cast full of photogenic performers, you could say the statuesque blond held a special place among the show's more cybernetically-inclined viewers.
