Factual error: During the scene where the helicopter leaves the hospital roof, a Canadian registration number is visible under the front doors. An aircraft which operates solely within the US, which is what would almost definitely happen for a city in Colorado, would legally have to have a US registration due to sabotage laws concerning the registration of aircraft. AVPR was filmed in British Columbia, Canada, which explains a Canadian registration number, since all Canadian aircraft registration begin with "C".

Continuity: When the guy with the predator gun shoots the gate at the end, so they go to the chopper, the wire fence keeps changing its shape in different shots.
