Ellen Ripley

Lt. Ellen Louise Ripley, usually referred to by her surname, is a fictional character and the original protagonist of the Alien film series, played by American actress Sigourney Weaver. Considered one of the greatest characters in science fiction film history, the character earned Weaver worldwide recognition, and remains her most famous role to date. Although she was originally conceived as male for the first Alien film, director Ridley Scott decided early in production to make her a woman. Alien (1979) and its sequel Aliens (1986) were heralded for challenging gender roles, particularly in the science fiction, action, and horror genres…Wikipedia
