Revealing mistake: When Will launches "Guardian," the window shows the Restore icon (two overlapping squares) in the title bar even though the app isn't maximized (desktop is visible around it).

Continuity mistake: When young Snow White places the flower crown on the girl, her braid swaps sides between shots.
Continuity mistake: The establishing shot of the post-credits scene shows the spot in bright sunlight. In the following shots, the building and wall on the left, as well as the ground, are in shadow. (02:09:00 - 02:28:21)
