Walt Disney refused to allow Alfred Hitchcock to film at Disneyland in the early 1960s, because Hitchcock had made "that disgusting movie, Psycho (1960)." Hitchcock's intended project is unidentified at this time, but it may have been for an episode of his television series.
Alfred Hitchcock was famous for his highly amusing opening and closing narratives. However, for each episode more than one opening and closing were filmed, as Hitchcock's famous jibes at the sponsors were unappreciated in the European markets. So for each episode, Hitchcock filmed two openings and two closings: one would be for American viewings (jokes about sponsors) and the second would be for European showings (jokes about Americans and not about sponsors). For most of the third season, Hitchcock even did the opening and closings in French and German, as he spoke both languages fluently.
