Continuity mistake: In the hotel scene when Van Damme is crashing through walls to escape the other Universal Soldiers who are shooting from outside, one shot from the inside of the room shows him hitting the wall with his left shoulder, but when the camera goes into the next room to show him coming through that wall, he is breaking through with his right shoulder.
Continuity mistake: When Luc Deveraux and Veronica Roberts are on the prison bus and Andrew Scott is chasing them on the truck/base of operations Andrew starts throwing hand grenades. Andrew throws one that lands inside the bus. Veronica has time to fumble around for it, pick it up, scream about it and throw it out of the window before it explodes. The rest of the grenades that Andrew throws explode in a couple of seconds like they are supposed to.
