During the fight inside Castle Grayskull, Skeletor runs past Teela and Battle Cat. Teela turns her head to the other side as if to follow his movement, but does so before he crosses her path.
As Ram Man rams a rolling boulder with his head he moves out of frame in one shot and into frame in the next, but the same background plate is used in both shots.
He-Man deflects two bolts from Skeletor's Havoc Staff and aims that at the two chains that are holding the Sorceress' arms. But he did not make any movements during this action to justify the bolts hitting two different targets.
When He-Man and Battle Cat first arrive at Basilia, Battle Cat appears to be walking on air.
After a second boulder is seen rolling down a gullet, Ram Man gives He-Man a warning. But the empty gullet is visible behind He-Man and the boulder is now rolling at him from a different direction.
When Battle Cat points out the whirlwind, it can be seen from behind that his mouth is not moving.
