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.
The scientific geniuses mentioned perihelion, which is the point in an object's orbit which is closest to the sun. They should have said perigee, which is the closest point to the earth.
