Visible crew/equipment: When Ms Price tries to fly on her broom and she is launched upwards and wipes-out on the floor, she is replaced by a very obvious and much younger stunt double.
Visible crew/equipment: At the end of the film, taking place in a sunny field, Paul holds the bedknob and in both of the final shots about 3 or 4 lighting screens are reflected.
Visible crew/equipment: When the rabbit jumps on Ms. Price's lap, she tells him to jump off. Watch the close-up and a stunt's red hand appears from where her belly is supposed to be and pushes the animal away.
Visible crew/equipment: When Ms. Price is riding her broom in the beginning, you can sometimes see that she is not riding a broomstick but instead a saddle-like mechanical object.
Visible crew/equipment: After the cat hisses at the children and Miss Price says they startled him, the cat is shown moaning and you can see a shadow moving across its head. It's not Miss Price, as she is up on the stairs, and it's not the children, as they are not close enough and are trying to keep their distance as they move towards the stairs. This is likely a crew member moving toward the cat in order to get it to react. (00:10:10)
