Creator Backlash: According to avowed atheist Margot Kidder, she and Howie Mandel didn't realize that Tribulation was Christian propaganda until they were nearly done filming, when the Antichrist goes on a Motive Rant. Apparently (and understandably), it was a Berserk Button for Kidder when people approaching and praising her performance.
The Other Darrin: Sam Bornstein played Franco Macalousso in the first film, which was later played by Nick Mancuso in the further three installments.
Dawson Casting: Fourteen-year-old Leona is played by a 22-year-old actress.
For the 1998 video game
Dueling Works: It came out alongside ONE., another sci-fi themed third-person shooter for the PlayStation with a One-Word Title and a similar gameplay format. Both games' trailers are even displayed in the same hall during June 1997 Electronic Entertainment Expo.
Recycled Set: One of the maps was later repurposed as the Downtown Minneapolis map for — of all games — Tony Hawk's Pro Skater! The game engine is actually the same (note that both games have the ability to play low-res music videos in the levels), and much of the early development work involved using Kincaid's model on a skateboard. The same game engine was also used later on by Spider-Man (2000).
What Could Have Been: The game was originally meant for two players, with Bruce Willis' Trey Kincaid as a supporter, but halfway through it was repurposed as a single-player game. Kincaid's dialogue are remnants of when he was supposed to be a secondary character.
