Aaron Stell (March 26, 1911 - January 7, 1996 in Los Angeles) was an American film editor who worked on To Kill a Mockingbird, Touch of Evil, and others. The Orson Welles picture proved difficult, Stell was not the initial editor but instead chosen for re-editing, and Stell noted Welles became "ill, depressed, and unhappy with the studio's impatience" in the process.
