Following the success of BAFTA-nominated, hand-drawn animated adaptation of Judith Kerr’s classic picture book Mog’s Christmas (HarperCollins Children’s Books), Channel 4 has commissioned a seasonal special based on Kerr’s picture book Mog’s Bad Thing. In Mog’s Bad Thing, Mog is the Thomas family tabby cat who always finds herself in big trouble. 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. Mog’s warm-hearted and funny adventures went on to inspire a further 17 picture books in the series, selling over four million copies worldwide and translated into 21 languages. First transmitted on Channel 4 in the UK at Christmas 2023, Mog’s Christmas was directed by Robin Shaw and written by Joanna Harrison.
