LOS ANGELES (AP) — Marcia Lucas, who won an Oscar as editor of the original 1977 “Star Wars” and was part of a group of women whose editing was essential to film’s New Hollywood era, has died, a lawyer for her family said Friday. She was 80.

Lucas, who was married to “Star Wars” creator George Lucas from 1969 to 1983, died Wednesday from metastatic cancer, attorney Deidre Von Rock said in an email to The Associated Press. She died in Rancho Mirage, California, surrounded by loved ones, Von Rock said.

Marcia Lucas was the editor on 1983’s “Return of the Jedi” and the pre-“Star Wars” George Lucas-directed films “THX 1138” and “American Graffiti.”

She was also part of the editing team for director Martin Scorsese’s 1970s films “Taxi Driver,” “Alice Doesn’t Live Here Anymore” and “New York, New York.”

Editor was a rare senior creative position where a woman could find a foothold in Hollywood. Marcia Lucas became one of several women whose work in the editing chair made sense of the work of the overwhelmingly male directors of the New Hollywood of the late 1960s through the early 1980s, including Dede Allen, editor of “Bonnie and Clyde” and “Dog Day Afternoon”; Verna Fields, editor of “Paper Moon” and “Jaws”; and Thelma Schoonmaker, editor of most of Scorsese’s films starting with 1980’s “Raging Bull.”

Lucas was often called the unsung hero of “Star Wars,” the original film that after sequels, prequels and spinoffs has come to be known by its subtitle, “A New Hope.”

She convinced her then-husband that he should have Obi-Wan Kenobi, played by Alec Guinness, die in his lightsaber battle with Darth Vader and become a spirit guide to Mark Hamill’s Luke Skywalker.

And she had to make sense of raw footage that could have been a mess in the wrong hands, including the climactic rebel attack on the Death Star.

“It was extremely complex and we had 40,000 feet of dialogue footage of pilots saying this and that. And she had to cull through all that, and put in all the fighting as well,” George Lucas told Rolling Stone in an interview a few months after the film came out. “Nobody really has ever tried to interweave an actual plot story into a dogfight, and we were trying to do that.”

Lucas was born Marcia Griffin in Modesto, California shortly after the end of World War II. She moved to Los Angeles with her mother after her parents divorced when she was a small child.

She began working as a film librarian and moved into working as an editor on commercials, trailers and promotional films. She was an assistant editor on the documentary “Journey to the Pacific” for Fields, who also hired George Lucas, then a film student at the University of Southern California.

The couple became engaged soon after. Their marriage would essentially end in 1982, but they kept their divorce under wraps until after the release of “Return of the Jedi” in 1983. Marcia Lucas was then married to Tom Rodrigues, a production manager at the Skywalker Ranch production center, from 1983 to 1993.

She is survived by her daughters, Amanda Lucas and Amy Soper, and grandchildren Felix Hallikainen, Aeliana Hallikainen and Knox Soper.

“Her influence on film is indelible, but those who knew her best will remember the way she made life feel more vivid, more beautiful, more fun, and more full of love,” a family statement said. “Her work was known for its emotional intelligence, rhythm, and humanity — a rare ability to find the truth of a scene and bring heart, momentum, and clarity to the screen.”
