George Tomasini was an American film editor, born in Springfield, Massachusetts, who had a decade long collaboration with director Alfred Hitchcock, editing nine of his movies between 1954 and 1964. Tomasini edited many of Hitchcock's best-known works, such as Rear Window (1954), Vertigo (1958), North by Northwest (1959), Psycho (1960), and The Birds (1963), as well as other well-received films such as Cape Fear (1962). On a 2012 listing of the 75 best edited films of all time, compiled by the Motion Picture Editors Guild based on a survey of its members, four films edited by Tomasini for Hitchcock appear. No other editor appeared more than three times on this listing. The listed films were Psycho, Vertigo, Rear Window, and North by Northwest.

Rear Window is a 1954 American mystery thriller film directed by Alfred Hitchcock and written by John Michael Hayes based on Cornell Woolrich's 1942 short story It Had to Be Murder. Originally released by Paramount Pictures, the film stars James Stewart, Grace Kelly, Wendell Corey, Thelma Ritter, and Raymond Burr. It was screened at the 1954 Venice Film Festival.
