* AllStarCast: Aside from Americans William Fitchner and Taye Diggs, the cast is full of fairly well-known (or soon to be well-known) British actors, including Creator/ChristianBale, Creator/EmilyWatson, ''Film/{{Braveheart}}'''s Angus Macfadyen, Creator/SeanBean, and one of the last roles of [[Film/DeepRed David Hemmings]].
* CompletelyDifferentTitle: Known as "Rebellion" in Japan.
* TheOtherDarrin: Preston's wife was played by two actresses. They'd shot the [[spoiler: execution scene]] first, but when it came time to shoot the other flashback they couldn't find the first actress and had to quickly find a substitute.
* ShootTheMoney: The interrogation scenes between Preston and Mary, despite simply being two people speaking to each other, were incredibly expensive. Mary required multiple dresses of various shades of pink and each scene required a smaller table than the one preceding it. Director Kurt Wimmer felt that it was absolutely necessary, despite squeezing the film's already tight budget, because the richer colors and the closing distance between the two characters showed that Preston was emotionally opening up and beginning to perceive beauty.
* The drug Prozium is a {{Portmanteau}} of existing drugs Prozac and Valium. Valium is from the category of anti-anxiety drugs known as {{BZs}} (Benzodiazepines), which slow down activity of the central nervous system by enhancing the effect of GABA, which is a neurotransmitter that has a general quietening effect on many of the neurons in the brain. Prozac is from the category of antidepressants known as {{SSRIs}} (selective serotonin re-uptake inhibitors), that increase levels of the neurotransmitter serotonin, which regulates mood and anxiety. This reflects the combined purpose of the drugs within the context of the film, because of 'equilibrium' - Father makes enough sense to explain it removes the highs and lows of emotion which is believed to be the cause of humanity's demise.
