Audio problem: (May only apply to the original VHS release.) When Scar has Zazu locked up in a cage, Zazu mentions Mufasa's name and Scar yells at him, "What did you say?" Right before Scar's actual line, whilst Zazu is talking, you hear Scar's "What did you say?" line very faintly in the background, even though Zazu has not even mentioned Mufasa yet.
Factual error: There are a lot of comments about the Harrier (technically speaking it is an AV-8B, a slightly different aircraft) flown by Arnold Schwarzenegger, but everyone's missed the obvious one. The terrorist with the AK47 is unaware of the fact that a Harrier is hovering just outside the window until he slowly turns and see it there. He does a double take when he sees the Harrier just five metres away! A Harrier is an incredibly loud aircraft; you can hear them from three kilometers away. At that range the floor would shake with the noise and he would have been in no doubt whatever that he had been under attack for some time.
Deliberate mistake: After the trilithium missile hits the sun, it is shown going out in real time from Veridian III. As the planet is relatively earth-like, it is several light-minutes away from the sun. The filmmakers wanted it to be obvious that the missile was successful, so they ignored the speed of light.

Other mistake: The kids dare each other in a decrepit water tower which is mysterious in a number of ways: 1) Draining the water causes a powerful vortex, but the water level is not going down. 2) No one seems to work the bottom valve, but the vortex comes and goes. 3) It is absolutely impossible that anyone could swim through such a vortex, but Stu does. 4) The rotten roof breaks under the weight of little Billy (the ice-cream excess?) but carries his brother who weighs about 4 times as much.

Continuity mistake: In the water tank sequence Cranston dives to the bullet holes to get air. When he dives down there is a camera shot looking up at him from the bottom of the tank showing that there is plenty of air left at the top, no doubt left there so that the actor would not drown. And; for the sealed tank to fill completely there must have been a way for air to escape rapidly from the top. When the tank was full water kept pouring in and would have escaped the same way. When Margo arrives there is no water coming off the top of the tank.
Plot hole: This TV movie uses a lot of flashbacks to the previous 4 installments, by having people saying to each other, "Hey, remember that time when we..." a bit more than usual. In the village of the Minotaur, Iolaus remembers the fight from Hercules and the Amazon Women where he dies. That is also the reason why this flashback is interrupted just before that point. But at the end of the Amazon Women story Hercules used magic to jump back in time and change history so that the whole adventure had never happened (next making sure that it would not happen all over again). Obviously they wanted to use some cool action footage from all the TV films. But Iolaus could not remember these events as it happened in some cancelled version of the future. (Hercules remembers, but he wasn't going to tell anyone, and that's what we have to go on).
Character mistake: When Guile promises to rescue the hostages while on camera with Bison he makes a point to mention Charlie by name to reassure him that he wasn't forgotten. Anybody who was in charge of a major recovery operation would know better than to mention a specific hostage that isn't already well known to the enemy because he just put a target on that hostage for further abuse. This was promptly shown in the following scene when Bison picked out Charlie to be transformed into a beast as a result of Guile identifying him as a personal friend.AD
