Marcia Lucas spoke about this in Jonathan Rinzler’s Howard Kazanjian book. She debunks the narrative that she is the sole reason for “saving” the film.
Many of us on here are aware of the downplaying or ignoring of Marcia Lucas’ contributions to the films in the official Star Wars history - and applaud content which illustrates and highlights her input - along with the input and work of others too… yet there is now a narrative where she is the sole reason for ‘saving’ the film? And the above words debunked that narrative? Huh.
It was all a collaborative process and George was very much involved in piecing it all together.
Indeed, and yet it is such a shame that some of the content out there which attempts to highlight the contributions of others to the Original Trilogy is somehow labelled as ‘lying, biased nonsense with misdirection and misinformation across the board’ along with false inferences that the editors somehow created Star Wars, or that such content is viewed to be an affront or insult to George, or ‘literally a lie’.
Especially so when one of those people who had a significant input on the Original Trilogy has seemingly been omitted / erased from the official Star Wars history.
The following passage of words by Marcia Lucas didn’t get much attention on social media (unlike the quotes re the Prequels and Sequels has over the past day or so) - yet they are worth putting up on here… it is the foreword written by Marcia for the book ‘Howard Kazanjian: A Producer’s Life’, by the late JW Rinzler:-
Seems like it is a good intriguing book - I hope people do read it (and not just Marcia’s quotes on the Prequels & Sequels).
As well as looking up other rare content where Marcia talks about her work and contributions on the Original Trilogy films…

It also touches upon the some of the people who contributed to / worked on the film - and were later written out of the official history of Star Wars - such as Lippincott himself, Gary Kurtz, and Marcia Lucas…
