Sigourney Weaver celebrates her 69th birthday on October 8, 2018. The three-time Oscar nominee has proven herself a capable leading lady in a variety of genres, including science fiction, fantasy, comedy, horror, and drama. In honor of her birthday, let’s take a look back at 15 of her greatest films, ranked worst to best.

Weaver made her film debut with a walk-on role as Woody Allen’s girlfriend in “Annie Hall” (1977). Her breakthrough came just two years later for Ridley Scott’s landmark sci-fi thriller “Alien” (1979). As Ripley, the lone survivor aboard a spacecraft besieged by a snarling, ferocious extra-terrestrial, Weaver broke down barriers for female action stars and helped launch a franchise that led to three sequels: James Cameron’s “Aliens” (1986), David Fincher’s “Alien 3” (1992), and Jean-Pierre Jeunet’s “Alien: Resurrection” (1997).

“Aliens” brought Weaver her first Oscar nomination as Best Actress, a rarity for the genre. Not to be typecast, she found further success in a variety of roles that didn’t require donning a space helmet. She pulled off the rare hat trick of receiving two Oscar nominations in a single year: one for the comedic “Working Girl” (supporting) and one for the biopic “Gorillas in the Mist” (lead). Despite winning Golden Globes for both, she left the Academy Awards empty-handed, losing to Geena Davis (“The Accidental Tourist”) and Jodie Foster (“The Accused”), respectively.

Weaver found further success on the stage, reaping a Tony nomination as Best Featured Actress in a Play for “Hurlyburly” in 1985. Her small-screen work also brought her three Emmy nominations as Best Movie/Mini Actress ( “Snow White: A Tale of Terror” in 1998, “Prayers for Bobby” in 2009, and “Political Animals” in 2012).
