Celebrating 50 years since the birth of the Mr Men and Little Miss books, Great British Bake Off host Matt Lucas tells the story of the colourful little characters who changed global publishing forever.

As well as charting the rise of a billionaire publishing phenomenon the books are mini morality tales. They are forever young because they are templates for tolerance, acceptance, gender equality, diversity, wellbeing and justice.

Featuring artists, collaborators, super fans, original archive and the behind-the-scenes story of how they are made, the film is a celebration and an insight into what it takes to create a children’s publishing icon and what the characters mean today.
