Today I checked a link a mate on Twitter made, and I found it very funny: welcome people to the Sci-fine: Geekdom’s Baddest Babes!
A few comments on that girls: a lot of them are not very hot, as Princess Leila, but other are really interesting… Here are my three favorites:
First of all: 
Claudia Black. She’s absolutely my favorite. Before reading that article in the Maxim webzine I haven’t realized she was also in Pitch Black; as a matter of fact, I know her from Farscape (which I saw only a couple of episodes) and Stargate SG-1 (followed all the 10 seasons). I really loved her character of Vala Mal Doran.
My second choice: Milla Jovovich. I watched all the three Resident Evil movies, but above all I loved her interpretation of Joan of Arc. Even my girlfriend likes her, unbelivable.
And third: Gillian Anderson. I inserted the Wikipedia link for completeness, but if you don’t know who she is, shame on you!
A really hot babe is also Tricia Helfer from Battlestar Galactica, but I hated her sexy character of Number Six/Caprica (not for her interpretation!), so she’s not in my first three 
If you’re not a Sci-fi fan, I’m linking some videos of the show mentioned above, just to have an idea.
Have fun!
