★★★☆☆

THE world of celebrated children’s author AA Milne and the creation of his beloved Winnie the Pooh stories are chronicled in this frightfully polite biopic from director Simon Curtis (My Week with Marilyn) that flirts with dipping its toes into darker waters but steadfastly clings to safe tropes and always with its top button firmly fastened.

We start off in 1941 where we find an ageing Milne (Domhnall Gleeson in questionable make-up and greyed hair) and his wife Daphne (Margot Robbie) living on their secluded East Sussex farm. They receive a telegram informing them that their son, CR Milne, is missing presumed dead after heading off to fight in World War Two.

We then jump back in time to Milne on the front lines of the First World War. He returns from the fighting a changed man; suffering from PTSD (popped balloons evoking sudden gunfire et al.), becoming increasingly sick of just making people laugh with his West End plays and the general hustle-bustle that comes with big city life.

He convinces his reluctant wife to move to the country for some peace and quiet and where his infant son, Christopher Robin (played by Will Tilston at the younger age, Alex Lawther as he gets older), can go on the childhood adventures he deserves with the support of loving nanny Olive (Kelly Macdonald).

Settling into the kind of serene life he craves, he is inspired to create Winnie the Pooh and the rest of his soon-to-be-beloved friends inspired by the stuffed animals with which his young son has become so enamoured. Unfortunately for Christopher — referred to by everyone as “Billy Moon” - his father uses his real name in the stories, turning him into one of the most famous boys in the nation.

Despite the obvious attraction of it exploring the world famous Pooh stories, it’s a film much more interested in the effect it has on a fractured family clinging on to peacefulness, not least the unwanted attention thrust upon a young boy who simply isn’t equipped to handle it and how his parents carry on oblivious.

If anything it takes a curiously bleak outlook on what these stories mean to the world once they’ve been put out there, conveying a somewhat confusing message for a film that ultimately wants us to celebrate these stories as immortally cherished tales; that the Winnie the Pooh embraced immediately by the public and has now stood the test of time for almost a century is in some way missing the point of what it truly means to the author and a son who, inadvertently or not, was used as a tool of innocence to sell the idea of an idyllic childhood in Milne’s Hundred Acre Wood.

It’s bolstered by almost uniformly moving performances; Gleeson plays Milne with a kind of damaged empathy that makes you feel like you get to know the author beyond the public persona. Macdonald is oftentimes heart-breaking as Christopher’s devoted caregiver and Tilston walks away with the film as the adorably sweet-natured young Christopher. It’s only with Robbie that the film makes a misstep; she’s miscast as Milne’s wife and never stepping out of the shadow of cold motherly cliché.

In spite of its darker leanings, the film remains too buttoned up to properly wrestle with those themes in any sort of lasting way, far too polite to ever dive head first into the murky waters into which the drama intermittently peers.

Wrapped in Ben Smithard’s handsomely old-fashioned cinematography and soaked in Carter Burwell’s perpetually swelling score, it’s an aesthetically and emotionally appealing but nevertheless fairly vanilla period biopic best suited to being enjoyed on a rainy Sunday afternoon with tea and biscuits.
