George Tomasini (April 20, 1909 – November 22, 1964) 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.

[1] 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).

[2] George Tomasini was known for his innovative film editing which, together with Hitchcock's stunning techniques, redefined cinematic language.

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'.
