Continuity mistake: When Grandma shows her bag with the mice inside to Bruno's mom, her grip on the bag changes between shots: sometimes she is grabbing the upper handle where the yellow threads are; others, the wooden part slightly below the threads; and yet in other shots she is grabbing the lower wooden part.
