Here's your chance to engage in a worthwhile debate: Who's the hottest "Sci-Fi Girl" (http://www.ugo.com/movies/top-50-hottest-sci-fi-girls)?
Sigourney Weaver, in the underwear scene in Alien, at #49? I disagree already.
EDIT: In light of TUE's post under mine I shall state that Barbarella should clearly be #1 on the list.
the number 1 spot is typical fanboyism, i would have put her more around 50-40
ignoring the actual placements I think everyone I'd want on the list is there.
It's a great list and I actually have a hard time seeing it as being in any sort of numerical order so much as it is a list of 50 sci-fi babes. Bonus points for having the space vampire from LIFEFORCE!
