Commentators such as Stephen Rebello and Bill Krohn have argued in favor of Bass' contribution to the scene in his capacity as visual consultant and storyboard artist. Along with designing the opening credits, Bass is termed "Pictorial Consultant" in the credits. When interviewing Hitchcock in 1967, François Truffaut asked about the extent of Bass' contribution, to which Hitchcock replied that in addition to the titles, Bass had provided storyboards for the Arbogast murder (which he claimed to have rejected), but made no mention of Bass providing storyboards for the shower scene.
