OMISSION:
During the scene in which Travolta (as Cage) is about to have his brain fried in the prison, we can see a cabinet/box with the inGEN logo on it. inGEN being the genetics company that brought dinosaurs back to life in Jurassic Park!!
Does this mean Face/Off exists in the same cinematic universe as Jurassic Park? And what does this mean about the possibility of genetically-recreated dinosaurs that can switch faces???
