A 23 May 1963 DV news item reported that actress Doris Day and her manager-husband and producer Martin Melcher planned to collaborate on Some Other Love, based on an original play by William Fairchild. As the story was set in London, England, early news items indicated plans to film location work abroad, and the 7 Jan 1964 DV named Mike Connors as Day’s co-star.
       A few months later, the title had been changed to Do Not Disturb, and Ralph Levy was signed to direct. The new Aug 1964 start date reported in the 27 Jul 1964 DV was repeatedly delayed as location plans moved stateside, and casting continued for nearly a year. According to an article in the 20 Jan 1965 Var, Do Not Disturb was one of several pictures affected by the Screen Actors Guild’s recent enforcement of labor laws heavily limiting the number of foreign actors filling supporting roles that could otherwise be played by Americans. Consequently, producer Aaron Rosenberg revealed that Day’s intended French love interest had to be rewritten for an available actor when their initial choice was rejected by U.S. immigration. Italian Sergio Fantoni eventually filled the role as “Paul Bellari.”
       The 10 Aug 1964 DV indicated that Peter L. Marshall was also considered to star, and additional DV casting items throughout production noted the involvement of Neil Carter, Richard Flato, Donald Lawton, Richard Peel, Clive Wayne, Terence Vliet, eleven-year-old Patrick Mischnaud, and his eight-year-old brother, Gerald Mischnaud.
       On 4 Dec 1964, DV announced that filming had been pushed back until after the holiday season to allow Twentieth Century-Fox Film Corp. to use their full studio space for the production of eleven television pilots. Principal photography officially began 11 Jan 1965, as stated in a DV production brief published four days earlier. The 12 Feb 1965 DV indicated that most work was done on Fox studio facilities in West Los Angeles, CA, with a few days spent at the Western Avenue backlot in Hollywood.
       Just over a month into the production schedule, director Ralph Levy was hospitalized with a virus, and George Marshall was brought on as a temporary replacement. Although a 2 Apr 1965 DV brief stated that Levy briefly returned to the set, Marshall was expected to complete the remainder of filming on his behalf, and he did not ask for credit. DV reported the conclusion of principal photography four days later.
       According to a 22 Dec 1965 Var news item and the 25 Dec 1965 NYT review, the highly publicized cameo of former U.S. Press Secretary Pierre Salinger was not included in the cut screened for the media.
       The film opened 24 Dec 1965 in several New York City and Los Angeles theaters, with general release in Jan 1966. Like Day’s other recent pictures, Do Not Disturb was a commercial success—a 4 Jan 1967 Var chart of the “Big Rental Pictures of 1966” indicated that ticket sales had earned Fox $3.5 million in domestic rentals to date.
