The title "Quantum Apocalypse" was the result of a joke: Writer Leigh Scott had an e-mail conversation with Dread Central reviewer Scott "The Foywonder" Foy (a frequent harsh critic of Sci-Fi Channel Original Films) about the Channel rejecting the previous title "Judgment Day". Foy remarked the reason that the title was rejected was that it didn't have a colon like many other Sci-Fi Channel films (such as "Caved In: Prehistoric Terror" and "Kraken: Tentacles of the Deep") and jokingly suggested the title "Judgment Day: Quantum Apocalypse". Scott liked the title "Quantum Apocalypse" and asked for permission to suggest it to the Sci-Fi Channel which approved it.
In the film, Ben is 36, and fortunately four years younger than his wife Lynne, who is 40. In real-life Randy Mulkey is more than twenty years older than Stephany Jacobsen.
Stephany Jacobsen (Lynne) had a role in the episode Incubator (2001) of the series Farscape (1999), which starred Gigi Edgley (Trish).
