Early life and education
Trainor was born on July 8, 1952 in Chicago, Illinois.1 She attended San Diego State University, where she studied broadcast journalism.1 After graduating she worked as a broadcaster at San Diego radio stations KSDO and KCBS before transitioning to acting.1
Career
Trainor made her television debut in 1983 in the Cheers episode "Father Knows Last."1 Her film debut followed the next year in Robert Zemeckis's Romancing the Stone (1984), opposite Michael Douglas and Kathleen Turner.1 The role introduced her to Zemeckis, to whom she was then married, and launched a pattern of recurring collaboration with him.
Her first prominent role was Irene Walsh, the mother of the young adventurers, in The Goonies (1985), directed by Richard Donner from a Steven Spielberg story.1 The film was later selected by the Library of Congress for the National Film Registry as culturally, historically, and aesthetically significant.1
Trainor became one of the most recognizable supporting faces in late-1980s franchise cinema. She originated the role of LAPD department psychiatrist Dr. Stephanie Woods in Lethal Weapon (1987) and returned for all three sequels: Lethal Weapon 2 (1989), Lethal Weapon 3 (1992), and Lethal Weapon 4 (1998).1 As television news reporter Gail Wallens she appeared in Die Hard (1988), carrying the character into Ricochet (1991); Die Hard was also selected for the National Film Registry.1 Further 1988 work included The Monster Squad and Scrooged.
After Ghostbusters II in 1989, she continued in major studio productions. Death Becomes Her (1992), Forrest Gump (1994), Congo (1995), and Executive Decision (1996) maintained her presence through the decade. Forrest Gump became her third National Film Registry title.1 Her other film credits include Grand Canyon (1991), Little Giants (1994), Action Jackson (1988), Moonlight Mile (2002), Freaky Friday (2003), and Cake: A Wedding Story (2007), which was her final screen appearance.1
Her television career ran in parallel with her film work. She played recurring character Estelle Becker on Remington Steele, the lead's mother on the Fox teen comedy Parker Lewis Can't Lose, Eve Lukens on the ABC drama Relativity, and Diane Evans on the science-fiction series Roswell.1
She also starred in the Tales from the Crypt episode "And All Through the House" (Season 1, Episode 2, June 10, 1989), playing Elizabeth, a woman who murders her husband on Christmas Eve and then finds herself menaced by an escaped mental patient dressed as Santa Claus.3 The episode was directed by Robert Zemeckis during their marriage.3 In a curious bit of scheduling, both "And All Through the House" and Ghostbusters II shared the cover of Fangoria #84 (July 1989), reflecting Trainor's simultaneous involvement in two high-profile genre productions.3
Ghostbusters II
In Ghostbusters II (1989), Trainor portrayed the Brownstone Mother, who hires Ray Stantz and Winston Zeddemore to perform as Ghostbusters entertainers at her son's birthday party.2 She leads the pair into the party room, observes that it has been a nightmare of a day, and informs them that there are fourteen children inside, all roughly four feet tall. The brief scene is one of the film's early comic sequences establishing the Ghostbusters' diminished post-1984 status, reduced to performing at children's parties. The Brownstone Boy #2 at the party was played by Jason Reitman, son of director Ivan Reitman;2 Jason Reitman would later direct Ghostbusters: Afterlife (2021). Trainor's appearance in Ghostbusters II came during the peak years of her career, when she was simultaneously working on Die Hard, Back to the Future Part II, and the Tales from the Crypt episode "And All Through the House" all within the same production period.1
Personal life
Trainor married director Robert Zemeckis in 1980. Together they had one son, Alexander. They divorced in 2000 after twenty years of marriage.1 Several of Trainor's highest-profile credits, including Romancing the Stone, Back to the Future Part II, Death Becomes Her, and Forrest Gump, were directed by Zemeckis during the course of their marriage.
Death
Trainor died of pancreatic cancer on May 20, 2015, at her home in Montecito, California. She was 62.14
