Trivia: During the end credits, we see a bold promise that Doctor Detroit would return in "Doctor Detroit II: The Wrath of Mom" (spoofing the title of Star Trek 2: The Wrath of Khan). This was probably just a gag, as Universal Pictures did not have high expectations for Doctor Detroit, and the film was a critical and box office failure, so no sequels were ever discussed. but to this day, Dan Aykroyd fans still ask him about the Doctor Detroit sequel. While he quickly dismisses any notions of a sequel, Aykroyd does, in fact, consider Doctor Detroit his most important film, for personal reasons: "Obviously it's the most important movie of my career. It's the one where I met my wife. It led to three kids and 30 years of marriage, so it's a pretty important movie for me. But I don't see Universal stepping up to that particular one." (Dan Aykroyd, 2013).
