Other mistake: When Stryker is killed at the end, it shows him lying on his back. Then, it cuts to a shot that shows the name on the back of his uniform. Who turned him over? (01:48:06)
Continuity mistake: In the very last minute of the film, Cheetah (the chimp) drinks some water that was from the fountain of youth and instantly changes into a baby chimp. But the baby chimp is a different species - a monkey with a long tail - and appears fully grown for that type of monkey.
Continuity mistake: In the film's final scenes at the fuel storage facility, full sunlight is streaming through the overhead rafters. Moments later, it's completely dark and the plant's floodlights are all turned on. A few shots further on, the lights are off and it's daylight again.
