Revealing mistake: When the dog with its legs in plaster is walking across the passageway the first time you see it its back legs are moving although they're supposed to be crippled.
Continuity mistake: When Esme runs to the camera then turns and runs back, she has a light pink handkerchief in her back pocket. When she climbs the balcony it is still there then when she jumps from the balcony and the suspenders stretch it has vanished.
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.
Continuity mistake: When Esme lands on the balcony before inflating you can see that her shoes are missing and her feet are pink and rubbery. This is odd because in the previous scene she had shoes on and now they've suddenly disappeared. Her feet being pink is also spoiler to the inflation as her inflated balloon body has pink feet.

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.
Revealing mistake: At 77.03 Esme jumps and the suspenders slack like cloth. This shows that the suspenders are made of cloth not elastic.
