An apparently unusual aspect to Hitchcock’s work method was his entrusting the viewing of dailies to editor George Tomasini and script supervisor Marshall Schlom. “He never went to look at this film,” Schlom asserted. “After dailies, George and I had to come back and tell him what we thought was right or wrong. He knew what he had.” Tomasini, having worked on The Wrong Man, Vertigo, and North by Northwest, was one of the handful of collaborators in whose taste and instincts Hitchcock placed implicit confidence. That track record notwithstanding, Tomasini was only paid $11,000 to edit Psycho.
