Revealing mistake: When Doctor Detroit and his girls make their escape from the automobile salvage yard, they drive a wrecker straight through a large sliding wooden gate, which punches a perfectly clean outline of the truck and Doctor Detroit through the gate. Problem is, the resulting (pre-cut) hole does not match the dimensions of the wrecker or Doctor Detroit at all. In fact, at the point of impact, the stuntman playing Doctor Detroit hugs in close to the wrecker for protection as it plows through the gate, and the outline of his body just magically opens up two feet away from him.Charles Austin Miller
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).
