- Deleted Scene: A deleted scene featured H. G. Wells meeting a punk who was playing extremely loud boom box music on a bus in San Francisco. The idea was later reused in Star Trek IV: The Voyage Home, which was co-written by Nicholas Meyer.
- Dueling Works: It came out a few months after another Jack the Ripper-themed mashup, Murder by Decree.
- Playing Against Type: Malcolm McDowell, who thanks to various prior roles generally gets cast as a bit of a psycho nutcase or otherwise amoral type, plays the rather sweet, slightly naive Wells — in a movie with Jack the Ripper. It helps that he does indeed bear quite a resemblance to the real Wells.
- Prop Recycling: The scenic elevator in the Hyatt Regency Hotel is the same elevator used in The Towering Inferno and High Anxiety.
- Real-Life Relative: Nicholas Meyer's girlfriend Shelley Hack plays a docent at the museum H. G. Wells transports into.
- Romance on the Set: Malcolm McDowell and Mary Steenburgen would marry and have 2 children together before splitting up in 1990. Steenburgen would later state, "Thank god for that movie, I have kids because of it!"
- What Could Have Been:
- The studio had wanted Richard Dreyfuss for H. G. Wells. Nicholas Meyer's first choice was Derek Jacobi.
- Myer wanted Edward Fox to play Jack the Ripper. Mick Jagger was also considered, but Meyer couldn't see him convincingly playing a Harley Street surgeon.
- The studio wanted Sally Field for Amy Robbins.
The series
- Short Run in Peru: In the US only 5 episodes of 12 aired, but all 12 episodes have been broadcast in Spain and Portugal.
