Hitchcock set and filmed "Frenzy" in London after many years making films in the United States. The film opens with a sweeping shot along the Thames to Tower Bridge, and while the interior scenes were filmed at Pinewood Studios, much of the location filming was done in and around Covent Garden and was an homage to the London of Hitchcock's childhood. The son of a Covent Garden merchant, Hitchcock filmed several key scenes showing the area as the working produce market that it was. Aware that the area's days as a market were numbered, Hitchcock wanted to record the area as he remembered it. According to the 'making-of' feature on the DVD, an elderly man who remembered Hitchcock's father as a dealer in the vegetable market came to visit the set during the filming, and was treated to lunch by the director.
