Benedict Cumberbatch and Claire Foy are returning to the world of Judith Kerr’s “Mog” picture books for Channel 4‘s animated special “Mog’s Bad Thing.”

Cumberbatch will reprise his role as Mr Thomas opposite Foy as Mrs Thomas while “Bridgerton’s” Adjoa Andoh also returns as the narrator alongside Amelie Law as Debbie and Teddy Skelton as Nicky.

The cast, who previously appeared together in the animated special “Mog’s Christmas,” also for Channel 4, will be joined this time by John Thomson (“Break Clause”) as Mr Bunce, Katherine Parkinson (“Rivals”) as Mrs Ramsbottom, Mawaan Rizwan (“Juice”) as Ali and Amelia Theodorou as Amy.

“Mog’s Bad Thing,” which is directed by Robin Shaw (“The Tiger Who Came to Tea”) and produced by Lupus Films (“Kensuke’s Kingdom,” “The Snowman and The Snowdog”), will once again follow Mog, the Thomas family tabby cat, as she finds herself in big trouble.

“The family are hosting a cat show in their garden which should be Mog’s chance to shine, but in all the excitement she does a ‘bad thing’ which means she hides in the attic feeling sorry for herself and misses the start of the show,” reads the synopsis. “Can Mog find a way to leave her hiding place, make her family proud and save the day?”

“Mog’s Bad Thing” is written by Joanna Harrison based on Kerr’s books, which have been translated into 24 languages and sold over 4 million copies worldwide. There are 17 books in the “Mog” series, which was inspired by Kerr’s own family cat.

Ruth Fielding and Camilla Deakin produce for Lupus Films. The animated special was commissioned for Channel 4 by Gwawr Lloyd, interim head of drama.

Serious Kids distribute “Mog” for theatrical and TV worldwide, outside of the U.K. Theatrical distribution will be announced in due course.
