Katz was born in Los Angeles on October 25, 1942. She attended UC Berkeley and went on to UCLA where she received a masters in film. Her husband Willard Huyck met George Lucas at USC and the three later became a trio of collaborators.

Katz teamed with her husband and Lucas on many projects. She is best known for co-writing the Lucas-directed classic American Graffiti starring Ron Howard. The film earned Katz, her husband, and Lucas an Oscar nomination in 1974 for Best Screenplay.

In addition to the coming-of-age comedy, Katz and her husband collaborated on numerous projects including the Steven Spielberg-directed Indiana Jones and the Temple of Doom. She also co-wrote Messiah of Evil, French Postcards, Best Defense, and Howard the Duck, which were all directed by Huyck. In 1994, the couple teamed with Lucas once again for Radioland Murders.
