Early life and education
Weaver was born to Sylvester "Pat" Weaver, the NBC television executive who served as the network's president from 1953 to 1955 and is credited with creating The Today Show and The Tonight Show, and English actress Elizabeth Inglis. Her uncle was the comic actor Doodles Weaver. She attended the Brearley, Chapin, and Ethel Walker preparatory schools in New York. Standing nearly six feet tall by her teens, she was teased by classmates and coped by becoming a class clown, a habit she credits as the seed of her acting career. At age 14 she changed her first name from Susan to Sigourney, after the minor character Sigourney Howard in F. Scott Fitzgerald's The Great Gatsby.1
She earned a BA in English from Stanford University in 1972, where she took part in the experimental theater group The Company, then completed a Master of Fine Arts at the Yale School of Drama in 1974. At Yale her contemporaries included Meryl Streep and the playwright Christopher Durang, who wrote roles for her in several of his works. Her early professional career was rooted in the New York stage: she made her Broadway debut in 1974 in The Constant Wife opposite Ingrid Bergman, performed in Durang's off-Broadway plays, and in 1977 appeared in John Guare's Marco Polo Sings a Solo, produced by Joseph Papp at the Public Theatre. She would later earn a Tony Award nomination for the 1984 Broadway production of David Rabe's Hurlyburly.16
Career
Weaver's film breakthrough came when she was cast as Warrant Officer Ellen Ripley in Ridley Scott's Alien (1979), after a brief appearance in Woody Allen's Annie Hall (1977). Ripley became one of the most influential heroines in science-fiction cinema, and Weaver reprised the role in Aliens (1986), Alien 3 (1992), and Alien Resurrection (1997). Her performance in Aliens earned a rare Academy Award nomination for Best Actress in a science-fiction film.6
The late 1980s marked the peak of her dramatic stardom. In 1988 she starred as primatologist Dian Fossey in Gorillas in the Mist and as the ruthless executive Katharine Parker in Working Girl. The two performances earned her simultaneous Oscar nominations (Best Actress and Best Supporting Actress) and two Golden Globe wins in the same year, a first for any performer.7 Her wider filmography includes The Year of Living Dangerously (1982), Dave (1993), Death and the Maiden (1994), The Ice Storm (1997, for which she won a BAFTA Award for Best Supporting Actress), the sci-fi comedy Galaxy Quest (1999), The Village (2004), and voice work in WALL-E (2008).
In 2009 she reunited with director James Cameron, who had directed her in Aliens, to play Dr. Grace Augustine in Avatar, then the highest-grossing film of all time. She returned to the franchise in Avatar: The Way of Water (2022), in which she voiced the teenage Na'vi character Kiri, and continued the role in Avatar: Fire and Ash (2025). Her later work also includes television roles in Prayers for Bobby (2009) and Political Animals (2012), both of which brought Emmy nominations.1
Weaver has continued to work steadily into her seventies. In 2024 and 2025 she made her West End stage debut as Prospero in Jamie Lloyd's production of The Tempest at the Theatre Royal Drury Lane in London.8 Announced and upcoming projects include the film The Mandalorian and Grogu (2026)9 and Useful Idiots, a New York-set thriller co-starring Meryl Streep.10 Among many honors, she has received a star on the Hollywood Walk of Fame (1999), the International Goya Award, and the Golden Lion for Lifetime Achievement at the 81st Venice International Film Festival in 2024.11
Ghostbusters
Ghostbusters (1984)
Weaver portrays Dana Barrett, a cellist living at 550 Central Park West whose refrigerator becomes a gateway for supernatural forces.2 She auditioned for the role by acting like a dog. To prepare, she took cello lessons. On the first day of filming at the New York City Public Library, she visited the set to introduce herself to Bill Murray; Murray responded by picking her up and carrying her down Fifth Avenue while addressing her by her real name, "Susan." Throughout production Murray would regularly sneak up behind her during scene preparations and goof around, tickling her or lifting her.
During filming Weaver improvised the line describing Peter Venkman as a "game show host" in place of the scripted "used car salesman." For the Terror Dog climax, she was sealed inside the charred Terror Dog prop. Director Ivan Reitman stretched the sequence's apparent length by repeating shots from multiple angles. As Harold Ramis noted in the special features of the Ghostbusters anniversary DVD, Weaver's presence added an air of class to the entire cast.12
Regarding the script, Weaver described it at the time as having "great heart and great humor" and praised Ivan Reitman as "a real craftsman."13
Ghostbusters II (1989)
The road to Weaver's return in Ghostbusters II was contentious. Columbia Pictures initially attempted to avoid paying her a share of the first film's profits, and she threatened litigation. Early drafts of the sequel removed Dana Barrett entirely, replacing her with a new character named Lane Walker; Bill Murray participated in auditions for the Lane Walker role. Later drafts restored Dana to a cameo appearance, and ultimately she was reinstated as the main romantic lead. Weaver was ultimately offered a flat fee of $1 million to appear in the film.
Her final scene to be filmed was the intimate dinner between Dana and Peter at Armand's Restaurant. That scene was later cut from the theatrical release.
Ghostbusters: The Video Game
Weaver did not reprise Dana Barrett for Ghostbusters: The Video Game (2009).14 According to Vivendi Executive Producer John Melchior, she was never contacted about the project. Terminal Reality Creative Director Drew Haworth stated publicly that she had turned down an offer to participate; Melchior disputed this. Reports also indicated that upon learning Bill Murray had agreed to voice his role, Weaver attempted to join the project, but development had progressed too far for her to be incorporated.
Ghostbusters: Answer the Call (2016)
In the 2016 reboot directed by Paul Feig, Weaver appears in a cameo role as Dr. Rebecca Gorin, the mentor of Jillian Holtzmann (Kate McKinnon). Several earlier cameo concepts were developed before the final version: one draft had Weaver as an unidentified woman who approaches the Ghostbusters' vehicle during their city patrol, tells them she believes in them, then either lies down on the ground or repeats the line to someone else. Another draft placed her in a group of women gathered outside the Firehouse giving conspiratorial thumbs-up to the team after they save the city.
The Rebecca Gorin scene was reportedly cut from an earlier edit of the film because it was deemed non-essential to the story, then restored for the theatrical release.
Ghostbusters: Afterlife (2021)
Weaver reprised her role as Dana Barrett in Ghostbusters: Afterlife, appearing alongside returning cast members including Bill Murray, Dan Aykroyd, and Ernie Hudson in the film's third act.
IDW comics references
The IDW Publishing Ghostbusters comics include several visual and textual nods to Weaver. In the "Visitation" backup story across Ghostbusters Volume 2 issues #7 and #8, a teacher character is visually based on her likeness.15 The Regular Cover of Ghostbusters 101 #1 includes a map credit referencing Sigourney Weaver.16 On page 11 of Ghostbusters Year One issue #2, an official 8x10 photograph of Weaver in costume as Dana from the first film appears on Peter Venkman's locker door.17 In Ghostbusters Year One issue #3, Dana's outfit in one scene is modeled on a costume worn by Weaver's character Lauren Slaughter in the 1986 film Half Moon Street.18
Personal life
Weaver married theater director Jim Simpson on October 1, 1984, the same year Ghostbusters was released. In 1996 the couple co-founded The Flea Theater, an off-off-Broadway company in Manhattan. They have one child, Charlotte "Shar" Simpson, born in 1990, an author and educator at Columbia University's School of the Arts. Weaver is a longtime environmental and conservation advocate and serves as an honorary chairperson of the Dian Fossey Gorilla Fund, an outgrowth of her work on Gorillas in the Mist.1
