1) Kristen Bell - Leia Organa (Solo)
In what is surely the pinnacle of her career, Veronica Mars actress Kristen Bell featured in 2008 comedy film Fanboys in a role that saw her dress up as everyone's favorite Jabba-strangling slave girl, Princess Leia. The movie revolves around a circle of geeks (a group of which is termed 'a Roddenberry') that plan and execute a mission to break into Skywalker Ranch and steal a not-yet-released copy of The Phantom Menace for their terminally ill friend. The photos released of Bell in costume helped to generate a lot of male attention for the movie across the internet.
Since 1983, Carrie Fisher's costume has gained a fanbase of its very own and it is now the go-to outfit for any self-respecting sci-fi sexypants or come-hither cosplay aficionado. There are usually so many re-creations of the famous outfit that conventions often hold 'group Leia' photographs. Bell certainly seems to have something that appeals to the wispy-bearded denizens of geekdom as she was voted 4th sexiest woman on television by the comic-loving magazine Wizard. We don't know about you, but she's the hottest rebel scum we've seen for a while.
