Peroni was Brokeback Mountain’s original film editor. She died at her home just as shooting of the film was being completed. Longtime colleague Dylan Tichenor completed the film, which is dedicated to her memory.

Best known for her working relationship with Robert Altman [pictured with her], Peroni edited eight of his films, including The Player, for which she received the Oscar nomination in 1993. Among her other credits were Tim Robbins’ Cradle Will Rock, Nora Ephron’s Michael, and episodes of the HBO series The Wire. She was assistant editor of Martin Scorsese’s epic The Last Temptation of Christ.

In a rare 1993 interview, Ms. Peroni said, “…when you screen the dailies, you react to something—a glance between two actors that came out of nowhere—where something magic happens. If you’re lucky, you have something like that in every scene that you can focus on.”
