Wallace & Gromit: The Wrong Trousers (1993)
1 suggested correction
Continuity mistake: In the beginning Gromit is pouring tea and there is a teacup and toaster near the pot. Gromit sets it down, gets the mail, and then comes back. When he comes back, the cup is much further away from the teapot and the toaster is on the other side of the table. No one has been in the room since Gromit left.

Question: How was the rain scene accomplished?
Answer: It was added at the edit. During the animation, the animators just made little sprinkles on the characters so it would look like the rain actually hit them.
