Here is a list of the top five malign-posterior (cough, bad-ass) females in SF movies, according to Jessica Martin at SF Crowsnest. The said women are the "five strongest, scariest, toughest women ever to fight their way across the screen." They include:

• 5. Angelina Jolie in Wanted
• 4. Michelle Pfeiffer in Batman Returns
• 3. Linda Hamilton in Terminator 2: Judgment Day
• 2. Uma Thurman in Kill Bill
• 1. Sigourney Weaver in Aliens

The article (with a much larger budget) includes a summary of the movies and females' (movie) parts therein.

Some of you probably are asking, what about Loretta King Hadler in Ed Wood Jr.'s Bride of the Monster? My answer is: I don't know. I'm just a bloggist.
