Peroni was born in Manhattan, New York City and grew up in the borough of Queens. Her collaboration with Altman extended over eight films. Altman said of Peroni "I trusted her totally with everything, I was planning on using her in the next film. She and I saw very much the same way — we just read each other so well." She was nominated for an Academy Award for Best Film Editing, the BAFTA Award for Best Editing, and the American Cinema Editors Eddie for her work on The Player. In his obituary, Tony Sloman discussed this film's editing: Peroni's work on Short Cuts has been discussed by Krin Gabbard, who wrote, "Altman has invited his audiences to provide connections among scenes that float loosely about each other at the same time that he has benefited from the intelligent choices made by the film's editor Geraldine Peroni." Peroni was found dead at her home in 2004. Her death was ruled a suicide by the New York coroner, a fact disputed by her family. She was in the midst of editing Brokeback Mountain. Dylan Tichenor completed Peroni's work; he later said, "I learned to edit from her, when she was Robert Altman's editor and I was her apprentice on The Player, and I worked with her for five years. While she was cutting Brokeback Mountain, she passed away rather suddenly, tragically. The first month was really difficult, seeing the work she'd done, all her selections and knowing her thinking behind it. Soon, it got to be cathartic and good to spend this time with her- I found myself thinking about her all the time through this process and it was a gift to me in that way." Tichenor and Peroni were nominated for numerous editing awards for Brokeback Mountain, including the BAFTA Award and the American Cinema Editors Eddie. The Wire episode "Back Burners" was dedicated to her memory. The credits of Brokeback Mountain also read "In Loving Memory of Geraldine Peroni".
