Second and final film produced by Tri Star Pictures under Lang Elliott's direction; Elliott would later sell Tri Star Pictures to Victor Kaufman when he made a joint venture consisting of Columbia Pictures, HBO, and CBS. Kaufman relocated the company from Atlanta to Burbank, and refurbished the company name and logo.
You know what I think? I think there's someone here who doesn't want anyone to know that there's someone here who might be someone that's a killer.
Inspector Winship: You know what I think? For a short person, you have long sentences.
At the end of the movie as Winship and Tart are driving away a wookalar appears in the back of their vehicle. Yet when there is a long shot of the vehicle it is very clear there are only two people in the vehicle.
During the main title sequence, the cartoon version of Inspector Winship (the Don Knotts character) is blowing on a tuba when the music credit comes up. The director of photography's name appears when two flashlight beams cross.
The television version which first aired in the early '80s included an extra scene, set in the dining room of Morley Manor. Inspector Winship and Dr. Tart switch identities trying to fool Mistress Phyllis and her staff.
