Continuity mistake: When Marisa stands up in front of the slide projector, her back is to it. However, when it shows her shadow on the slide, it is her profile that is shown. (00:07:25)
Continuity mistake: After Norville is punched by the Finnish stockholder, Amy walks in to see Norville holding an ice pack over a red mark on the side of his head. Part way through the scene, the red mark is gone.
Visible crew/equipment: At the end of the movie, as everyone reveals who they really are, when the girl reveals herself to actually be Detective Putrid you can see a hand reach up behind him and place his hat on his head. It could have been an intentional joke for the hat to suddenly float onto his head, but the hand probably wasn't supposed to be there.
Continuity mistake: Danny's hair keeps changing, when he comes out of the pool.
Plot hole: When Lalaina is in her depressed "Bell Jar" phase, she's complaining to the psychic hotline counselor that she's freaked out by the idea of having kids because she "can't even take care of a Chia Pet". But earlier in her documentary, she'd talked about how starting at age 13 she had to become the responsible one, buying food, taking care of and parenting her siblings. Which contradicts the portrayal of her as someone who can't take care of anything.
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).
Visible crew/equipment: When the spheres fly through the air you can see a "dot" following which is the camera.

Continuity mistake: In court, the camera shows Susan to judge her reaction to the lawyer talking, and she is sitting upright in her seat. It then changes to Dori, who is sitting right next to Susan. If you look in the bottom left hand corner however, you'll see that Susan is no longer sitting upright, and is instead leaning on Dori. There would be no time however for Susan to lean on her mother in the time the camera takes to move to another shot.
Continuity mistake: When the doctor is telling Al her diagnosis, the pencil on the clipboard disappears and reappears as the camera angle changes between her and Al.
Revealing mistake: As Mary, Sam, Jarvis and Andrew are speeding away from the TV station, one of the boys from the UFO crashes his bike head first into the car. This causes the boy to crash through the window. When he does this the window shatters like a plate glass window instead of the safety glass that is a standard to be used for vehicle windshields.
Continuity mistake: Meg Ryan and the bloke she was going to marry first were picking out colours for the house and he points to one but when he mentions later on he points to a different one.
Continuity mistake: When David Spade first takes a flyer for the pit party, he folds it half length wise and width wise, forming a quartersheet before placing it in his coat. When he later removes the flyer from his coat, it's been folded twice lengthwise, forming a long skinny strip instead of a quartersheet.
Revealing mistake: When the killer is up in the radio tower, he tries to force the man up the ladder. He brandished a revolver and you can hear the hammer being cocked back. It shows the revolver more and you can see the hammer is still down.
Revealing mistake: While Noro, a member of a shoeless society, is doing his uphill training you get a glimpse of his shoes, in spite of all efforts to hide his feet in the grass. (00:53:30)

Continuity mistake: When they are in the bar in Broken Hill, Old Shirl comes over and slaps her right hand down on Bernadette's. Then, in the next camera shot, it's her left hand.
