Production
The film is based on the 1965 debut novel Three for the Wedding by writer Patte Lee Mahan, which the Los Angeles Times called "a highly entertaining and amusing book." Trident Productions, a company established by director Delbert Mann, producer Douglas Laurence and writer Dale Wasserman, bought the film rights. Mahan agreed to write the screenplay and Charles Walters was originally slated to direct. The film was originally entitled Three for the Wedding, then This Way Out, Please before its final title of Doctor, You've Got to Be Kidding!. Sandra Dee selected the role of Heather instead of a part in a film shooting in London with Warren Beatty. This was Dee's first film after leaving Universal Studios, where she been under exclusive contract for ten years. She hoped the role would assist in her transition to more mature screen roles. George Hamilton was in a highly publicized romance at the time with Lynda Bird, daughter of president Lyndon Johnson. Doctor, You've Got to Be Kidding! marked Celeste Holm's first film since Bachelor Flat (1961). She said: "It's kind of an Italian comedy set in Glendale. Like most Italian comedies, it's based on a tragic truth. When the film opens, a young girl is unmarried and pregnant." Reception
After the film was previewed, MGM commissioned Phillip Shuken to write a sequel to star Hamilton and Dee, but the sequel did not materialize. References
