Revealing mistake: Every time there is a wide shot of the dragon flying it never flaps its wings. But when there is a close up, it is flapping its wings. (00:28:10)
Revealing mistake: Right after Xayide dies we see a shot of two monsters. One of the monsters explodes and the particles from the explosion hit the other monster making it break in half before it explodes itself. (01:15:25)
Revealing mistake: When the red laser is beaming Bastian we can sometimes see that the beams aren't even touching Bastian. (00:39:20)
Revealing mistake: When all the egg warriors are splitting you can see the eggs are cracked even before they split. (00:42:40)
Revealing mistake: Right after Atreyu discovers that Xayide is stealing Bastian's memories we see Atreyu and Falcor sitting on a cliff with an entire landscape in the background. It is easy to see the whole thing is fake, cause the camping place which they sit on shimmer and moves. The camping scene has been shot earlier and is now placed on a fake background, and someone is adjusting the picture. (01:00:15)
Revealing mistake: When Xayide and the monster are sinking to the ground it is obvious the scene is being played backwards as the last monster has leaves falling up from the ground onto it. (01:07:30)
Revealing mistake: When one of the monsters shoots out of the floor, it comes through what seems to be a square plate covering the hole under it. It is visible because the plate gets pushed up and we can see the edges of it. (00:18:25)
Revealing mistake: When Tri Face switches his face we see that the scene is suddenly cut from a doll to a human as his collar changes during the shot. (00:14:15)
Revealing mistake: When Bastian dives, you can actually see that it is a grown up stunt double. (01:18:20)
Revealing mistake: When Falkor is talking with Atreyu and says "Bastian is losing himself with every wish," you can see that Falkor hasn't got any body. (01:01:00)
Revealing mistake: When Atreyu lies dead, right before Bastian awakens him, you can see his neck pulsate. (01:12:20)
Revealing mistake: When the ground around the empress' castle is tearing apart you can see a tree falling down. However you can also see the wire pulling it down. (01:08:00)
Revealing mistake: When the dragon is flying by the castle, the castle is shooting a laser at it as it flies by. Then the dragon explodes just as it flies out of camera angle. However it is that the explosion comes from the ground down by the edge of the castle, and not in the air where the dragon is flying. (00:28:40)
