Goofs

When Alan looks at the cupboard where there was a glass of milk, there are no milk spills which were shown in one of the previous shots, but they can be seen again later.

Aunt Agatha's corpse's position is changed between two continuous shots in the film after it is thrown into the wheelchair. There is also no blood present in the first shot of her corpse in the wheelchair.

At the start of the film, when the car is stopped, the background does not match the one shown in the shot before the car stopped.

When the car is driving at the start of the film, it is driving while it is dark outside, but shots where the car is closer clearly show it earlier, when there is more light.

The film is set in England, and the cars accordingly keep to the left-hand side of the road, but they are all left-hand drive cars.

When Alan is using a torch inside Evelyn's tomb, the motion of the light from the torch does not match the motion of the torch, indicating that the torchlight was supplemented by an off-camera light.

When the red foxes in the cage start to eat Aunt Agatha's corpse, it is obvious that it is not her corpse that they are eating, but instead raw meat covered in Aunt Agatha's clothing.

During Susan's first dance, a band member is singing, yet the music in the film is an instrumental.
