his storyboard precisely. Because of this ... [the shooting] went very professionally," and she told Stephen Rebello that "Mr. Hitchcock showed Saul Bass's storyboards to me quite proudly, telling me in exact detail how he was going to shoot the scene from Saul's plans". Bill Krohn has noted that Bass's 48 story board panels for the scene introduced all the key aspects of the final shower murder scene – most notably, the fact that the attacker appears as a silhouette, close-ups of a slashing knife, the shower curtain torn down, a shot of the shower head from below, Marion's desperate outstretched arm, and the famous shot of the transition from the drain hole of the bathtub to Marion Crane's dead eye. Krohn notes that this final transition is highly reminiscent of Bass's iris titles for Vertigo. Krohn also concludes that Bass did not literally direct the shower scene, proving Hitchcock's presence on the set throughout the shooting of that scene. Bass introduced the idea of using a montage of fast cuts and tight framing to render a violent, bloody murder as an impressionistic and nearly bloodless one. Hitchcock felt uncertain about Bass's conception of the scene fearing that audiences might not accept such a stylized and quickly cut sequence. In an interview with film historian Pat Kirkham, Bass recalled, "Having designed and storyboarded the shower sequence, I showed it to Hitch. He was uneasy about it. It was very un-Hitchcockian in character. He never used that kind of quick cutting; he loved the long shot [sic]". To convince Hitchcock that the scene would work as planned, eight days before shooting of the final shower scene, Bass used a newsreel camera and Janet Leigh's stand-in Marli Renfro to shoot footage on the set to plan the shots in more detail. Working with Hitchcock's editor George Tomasini, he edited this footage following the storyboards to show Hitchcock how the scene could work. In the end, Hitchcock gave his approval but, according to Kirkham, made two additions: a spray of blood on the chest of Marion Crane/Janet Leigh as she slides down the tiles, and a close-up of her belly getting stabbed. In 1964, Saul and his wife and creative partner Elaine directed the short film The Searching Eye shown during the 1964 New York World's Fair, co-produced with Sy Wexler. The Basses also directed a short documentary film called Why Man Creates
