Corrected entry: In one of the opening scenes, Stuart is sleeping on the top bunk, and George is in the bottom bunk. In a later scene, the night after the soccer game when Stuart and George are going to bed, there are no bunk beds. Stuart walks across to his own bed that is sitting on the floor, not on top of George's bottom bunk.
Corrected entry: Near the beginning of the film, Margolo pretends to have an injured wing and Stuart takes her in. The next day when Mrs. Little and Martha go for their stroll, Margolo flies onto the roof to strengthen her wing. This is all fine and dandy, but how can an injured vertebra be strong enough to place pressure on it the next day? Wouldn't Mrs. Little have suspected something fishy at the sight of this?
Corrected entry: When Stuart first gets in his brother's plane and he flies outside and crashes in the park the family runs to see if he is OK, but they forget the baby at home all by itself.
Corrected entry: If the Littles can hear Stuart and Margola speak, how come they can't hear Snowbell?
