Following the success of Channel 4 and Universal Pictures Content Group’s adaptation of Judith Kerr’s classic picture book Mog’s Christmas (HarperCollins Children’s Books) in 2023, Lupus Films has announced that Channel 4 has commissioned a seasonal special based on Kerr’s picture book Mog’s Bad Thing (1 x 24’). 

Lupus Films has additionally announced that it has appointed London-based Serious Kids as the worldwide distributor for theatrical and TV, outside of the UK.

The new film will have a theatrical premiere in the UK, paired with Mog’s Christmas, before Channel 4’s TV premiere in December 2026.

Produced by Ruth Fielding and Camilla Deakin for Lupus Films (Kensuke’s Kingdom, The Snowman and The Snowdog, The Tiger Who Came to Tea), written by Joanna Harrison (We’re Going on a Bear Hunt, The Tiger Who Came to Tea, Mog’s Christmas) and directed by Robin Shaw (The Tiger Who Came to Tea, Mog’s Christmas, We’re Going on a Bear Hunt) Mog’s Bad Thing is a funny escapade from Kerr’s Mog series of picture books about the lovable family cat, which have sold over 4 million copies worldwide.

In Mog’s Bad Thing, Mog is the Thomas family tabby cat who always 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. Can Mog find a way to leave her hiding place, make her family proud and save the day?

“We are thrilled to have the opportunity to bring Mog’s funny feline adventures to the big and small screen once more,” commented Fielding. “Following the success of our previous collaborations with Serious Kids on seasonal specials The Ghastly Ghoul and We’re Going on a Bear Hunt, we know that Mog’s Bad Thing is in safe hands and we hope that MIPCOM will result in a host of key pre-sales.”

“We are incredibly excited to join forces once more with the team at Lupus Films on this delightful film,” said Leila Ouledcheikh, Director of Global Sales at Serious Kids. “We have already secured a lot of key broadcast interest and look forward to talking to everyone at MIPCOM Junior.”

Gwawr Lloyd, Interim Head of Drama, added: “We’re delighted to bring Mog back in another beautifully crafted adaptation from Lupus Films. Judith Kerr’s stories continue to resonate with audiences of all ages, and Mog’s Bad Thing captures the warmth, humour and gentle mischief that makes Mog so beloved. Following the success of Mog’s Christmas on Channel 4, we’re excited to be working with such an exceptional creative team again to deliver another festive treat for families to enjoy together.”
