At the beginning of the movie, when Abdullah steals Wadjda's head scarf, her sandwich is in her left hand. In the next shot, after the fall, her sandwich disappears.
When Wadjda adds her name to her father's family tree, the position and shape of the scrap of paper changes between closeup and wide shots.
Wadjda kicks Abdullah's crate on its side and he starts putting his things back into it, but after the cut to another angle, it is instantly standing upright.
When Wadjda takes the bread out of the oven, mic equipment is visible on her waist, under her T-shirt.
The first part of the movie shows a group of girls at school doing ritual washing before prayer. One girl wipes her ear right after washing her arm. The proper sequence is: arm, then head (hair), then ear.
