5. Megan Fox

Megan Fox isn’t exactly a stranger to the sci-fi/fantasy genre having starred in the first two Transformers movies and the absolutely dreadful adaptation of Jonah Hex. The truth is, though, that most people didn’t expect this bombshell to be a real-life Trekkie at heart. Yet, there's a problem: We’re not sure if her Trek love is legit or just a façade to keep the basement-dwelling fans excited about her crappy movies.

If she's being genuine, there is no reason not to have Fox show up in a Trek sequel or an eventual TV show revival. Think about it—Whoopi Goldberg nabbed a part on The Next Generation just because she was a fan of the show. Giving an actress with actual sex appeal a brief cameo should be a no-brainer.
