Continuity mistake: When the bucket of glue falls on Esme's head and she is pushed into the police van, the glue is mostly covering her back. Later when she's in court it has solidified heavily over the front of her dress. Then as she walks up the stairs it's gone from the front of her dress.
Factual error: When the plane takes off, the flight attendants on board are standing doing a safety demonstration. In real life the take off gradient is much steeper meaning they would either be thrown against the floor or at least find it difficult to stand. Also due to FAA regulation it is forbidden for anyone to stand on take off.
