A selection of them will be teaming up with their trainers to showcase their purrfect acting skills and taking part in live training demonstrations.

A menagerie of owls, cats and a toad will return to the incredible sets they ‘acted’ on during production of the most successful film series of all time, led by head animal trainer Julie Tottman, who helped create the performances of more than 250 live creatures throughout all eight of the films.

Visitors to the Gryffindor common room set will find it occupied by a red Persian cat that played Hermione’s bandy-legged feline Crookshanks.

He will be joined by a maine coon cat that portrayed Filch’s partner in crime Mrs Norris and the 14-year-old toad that played Neville Longbottom’s pet Trevor.

Outside Privet Drive, visitors will be able to pose for a picture with a snowy owl that played Harry’s loyal companion and post deliverer Hedwig.

Animal trainers will hold flight demonstrations throughout the day on the studio’s backlot, showcasing the techniques they used during filming.

n The scene which required the largest number of birds to ‘act’ was the owlery scene in Harry Potter and the Goblet of Fire. Trainers took on the difficult task of teaching almost 80 owls to hoot, fly and sit still at the same time.

n Initial groundwork for animal training takes about three to five weeks; when a script first arrived, the Animal Department would begin fundamental training, develop questions and ideas about how the scenes would be shot and then work with the director to finalise training plans.

n Crackerjack, one of the cats that played Crookshanks, became very good friends with one of the rats that played Scabbers. In fact, he would often chase the rat around the sets even when the cameras weren’t rolling.

n Animals appeared in the Harry Potter film series in some unexpected places. Themed breakfast cereals, including Lunfrey’s Cheeri Owls and Honeydukes’ Pixie Puffs, were created especially for the films by graphic designers Miraphora Mina and Eduardo Lima.
