Marcia Lucas, an Oscar-winning film editor known for her work on the original 1977 “Star Wars,” has died at age 80. Multiple outlets report that her family’s attorney confirmed she died of cancer in Rancho Mirage, California, and that the cancer had become metastatic. Lucas won the Academy Award for Best Film Editing for “Star Wars: A New Hope,” which was edited with other credited editors as part of a team. She was also nominated for editing “American Graffiti,” and she worked on George Lucas’s earlier film “THX 1138.” In addition to “Star Wars,” reports say she edited “Return of the Jedi” in 1983. Some coverage also notes that her career included editing or supervisory roles on other major films, reflecting her broader work in the industry beyond her collaborations with George Lucas. Lucasfilm issued a tribute after her death, describing her as a key figure in the creation of “Star Wars.” She was previously married to George Lucas from 1969 to 1983, and her editing contributions are frequently cited as influential to the development of the franchise’s early sound and pacing.
