Corrected entry: In the beginning of the movie when we first see Flash Gordon he is reading a newspaper in his car, but he's holding the paper upside down. (00:04:15)
Corrected entry: Vultan refuses to take Flash and co. with him, because they 'already have much more than they can carry'. But all the Hawkmen evacuate immediately and would surely not have time to collect any equipment. Indeed, a group of Hawkmen is seen flying towards the camera carrying only their weapons. (01:15:55)
Correction: Which is exactly his point...they can only carry their weapons and a few minor items. They can't carry other people. Besides, he still doesn't want to help Flash and the others because he fears Ming.
Corrected entry: When Ming and Flash are talking in the Hawkmen city, Ming moves right to the edge of the pit. Given that Flash knew he was about to die, wouldn't he have pushed Ming into the pit? (01:19:10)
Correction: Given that it not impossible that he didn't, this is your opinion of how Flash should have acted, not a film mistake.
Corrected entry: When Flash and Vultan break through to the Ajax flight deck, the killing of the captain and his flight officers are never shown. Only a few faceless soldiers are killed. (01:30:35)
Correction: If every single event which occurred during Flash's visit to Mongo were shown, this film would be three days long. Just because we didn't see it happen doesn't mean it didn't happen.
Corrected entry: In the scene where war rocket Ajax is chasing Flash Gordon into the cloud, the general stops before the cloud and gives orders to electrify the cloud and extend nets to catch Vultan's body. The only problem is that he wasn't chasing Vultan and he has no idea about the pending surprise attack by Vultan on the other side of the cloud.
Correction: The captain (not general) says 'prepare skynets to catch Gordon's body'. He believes that Flash Gordon is hiding inside the cloud. Nothing to do with Vultan.
Corrected entry: After Nero gets winged, Flash and Vultan are seen hovering in the air looking down on War Rocket Ajax. They are to the right and slightly behind the rocket. When they decide to join the battle, they end up landing on the rocket from the front.
Correction: I submitted this mistake and I've since discovered I was wrong. Flash and Vultan land on the rocket from the rear.
Corrected entry: After Barin and Zarkhov have killed General Kala, the Colonel appears on the video screen and proceeds to report on how Flash Gordon is in control of Ajax. He asks General Kala to show herself on his screen. But surely he would be able to see Barin and Zarkhov, and therefore would raise the alarm? (01:36:45)
Correction: He's reporting in, but, at his end, he's just looking at a blank screen while making his report. He's asking Kala to switch on her camera so that they can see each other.
Corrected entry: Princess Aura shows Flash how to fly the spaceship they are in while traveling to Aboria. There are 2 levers. She tells him the left controls altitude, and the right controls direction. After Aura annoys Flash, he shoves the right lever forward, and the ship nose-dives toward Fridgia. That was the wrong lever.
Correction: She tells him the LEFT one controls direction and the RIGHT one altitude.
Corrected entry: When Dr. Zarkov's memory is being erased, the monitor screen shows various memories in reverse-chronological order as they are erased. A few times, however, the memories go out of sequence. In one instance we see memories of Zarkov working for NASA before we see the memory of him resigning. In another instance we see Zarkov's (presumed) wife die, followed by her funeral. We should have seen the funeral first. (Incidentaly, this entire memory-draining sequence is great for playing back one frame at a time.)
Correction: I think the woman we can see in the sequence of Zarkov's memory is not his wife but his mother, because the last sequence shows a little boy crying, who should be Zarkov at his birth.
Correction: Actually it's a broadsheet and he's simply folded it under because it's too big.
