George Tomasini was known for his innovative film editing which, together with Hitchcock's stunning techniques, redefined cinematic language. Tomasini's cutting was always stylish and experimental, all the while pursuing the focus of the story and the characters. Hitchcock and Tomasini's editing of Rear Window has been treated at length in Valerie Orpen's monograph, Film Editing: The Art of the Expressive. His dialogue overlapping and use of jump cuts for exclamation points was dynamic and innovative (such as in the scene in The Birds where the car blows up at the gas station and Tippi Hedren's character watches from a window, as well as the infamous "shower scene" in Psycho). George Tomasini's techniques would influence many subsequent film editors and filmmakers.
"Tomasini's most important work with Hitchcock was the memorable shower scene in Psycho (1960). Its aesthetic and dramatic accomplishment was achieved largely through the editor's skill. The completed forty-five second sequence that Hitchcock originally storyboarded was compiled by Tomasini from footage shot over several days that utilized a total of over seventy camera setups. From that mass of footage, Tomasini selected sixty different shots, some of them very short, through which he elected to rely heavily on the techniques of 'associative editing'."
