Marcia, Richard Chew, and Paul Hirsch won the Oscar for Best Film Editing at the 50th annual Academy Awards in 1977. Marica later served as an editor of 'Return of the Jedi'. She also gave George notes on other projects during their marriage in an unofficial capacity

Marcia worked with Martin Scorsese on "Alice Doesn't Live Here Anymore" and "Taxi Driver" before jumping into the "Star Wars" editing process after George Lucas was horrified by the first rough cut of the movie.

Marcia died on Wednesday from metastatic cancer. TMZ reports she passed peacefully at her home in Rancho Mirage, CA surrounded by loved ones.
