Other mistake: When Max is making his escape from the compound in the Interceptor, he turns on the blower to speed through the bad guys' camp. Here you can see everyone running at fast-forward speed.
Other mistake: Towards the end, Capt Williams blows up some buildings (or caravans) to try and stop Hart from continuing, and flies off. When Hart later stops, the same buildings are blowing up again. One could argue that it's being seen from a different perspective, but in the wide shot after Williams flies off, the car cannot be seen.
Other mistake: When Snake is injected, and his timer is set to 23:00, Hauk tells him the glider is waiting. The next scene has Snake getting into the glider, but when he radios in, Hauk says there's 21 hours left. Snake was pretty upset that he didn't get a full 24 hours; knowing his life is on the line, why would he take 2 full hours to walk out the door and over to the glider that was waiting for him? (00:24:00 - 00:24:55)
Other mistake: After the exploding head incident, Revok is captured at gunpoint. Minutes later, the man pointing the gun at Revok racks the slides; no cartridge is ejected, which means the entire time prior to this moment the handgun was useless, as there was no round in the chamber. Cocking the hammer, taking the gun from double-action to single action, would have achieved the Hollywood dramatic effect without a common sense error on gun functionality.
