Harry Potter: Animal Actors

The largest amount of animals on set on any given day was 60 animals for a scene in Professor McGonagall's classroom.

Robbie Coltrane, who plays Hagrid, once got a fruit bat stuck in his beard during a scene in Hagrid's hut.

The largest animal to be brought on set was a hippo.

The smallest animal to be brought on set was a centipede.

After filming 40 kittens to go on moving plates in Umbridge's office, the kittens went on to be domestic pets, with their new owners unaware of their famous origins.

There have been 250 animals used across the Harry Potter film series (not including insects).
