1. Sigourney Weaver
The ultimate female action hero, Sigourney’s performance as Ripley in the Alien tetralogy (yes, that's a thing) is, in a single word, kickawesometacular (yes, that's also a thing). Ripley is everything an action hero should be; smart, brave, pragmatic and entirely willing to throw herself into the fray when need be. Ripley is living (and cloned) proof that you can’t keep a strong woman down.
