Continuity mistake: They trick one witch with a record recording of a boy that is lost. H&G are thrown down by it and the witch picks up a branch and begins zooming off like it is a broom. Hansel is behind her, yet despite the witch traveling faster than he is running, somehow he suddenly gets in front of her and smacks her with his gun. (00:31:10)
Continuity mistake: When the white witch helps and cleans Hansel, the sun changes between shots.
Continuity mistake: Young Hansel and Gretel both get some scratches and cuts on their faces when lost in the woods before finding the candy house. But while they are staring at the witch roasting in the oven, the scratches on Hansel's face have disappeared, but Gretel's remain. (00:06:30)
Continuity mistake: When Gretel is attacked by the sheriff and some men she's wearing her leather jacket. When Edward comes to save her, the jacket's gone.
Suggested correction: The jacket gets removed by the sheriff and his men in the extended version. So it's not actually a mistake.
Continuity mistake: When Hansel says he left his dignity in that tree, he turns his head to his right. Then the shot cuts to another angle and suddenly he is looking down at his feet. (00:45:20)
