A popular myth emerged that ice-cold water was used in the shower scene to make Leigh's scream realistic. Leigh denied this on numerous occasions, saying the crew was accommodating, using hot water throughout the week-long shoot. All of the screams are Leigh's. Another myth was that graphic designer Saul Bass directed the shower scene. This was refuted by several figures associated with the film, including Leigh, who stated: "absolutely not! I have emphatically said this in any interview I've ever given. I've said it to his face in front of other people ... I was in that shower for seven days, and, believe me, Alfred Hitchcock was right next to his camera for every one of those seventy-odd shots." Hilton A. Green, the assistant director, also refutes Bass' claim: "There is not a shot in that movie that I didn't roll the camera for. And I can tell you I never rolled the camera for Mr. Bass." Roger Ebert, a longtime admirer of Hitchcock's work, summarily dismissed the rumor, stating, "It seems unlikely that a perfectionist with an ego like Hitchcock's would let someone else direct such a scene."
