The many adventures of the true Christopher Robin weren’t quite so bouncy, trouncey, flouncy, pouncy; fun, fun, fun, fun, fun as you might think.

Spoilers may follow.

What’s it about?

In the course of his 74-year lifespan, Alan Alexander Milne wrote seven novels, five nonfiction books and thirty-four plays. As an author, however, he is known simply as the creator of Winnie-the-Pooh.

Goodbye Christopher Robin is both the origin tale of that famous honey-loving bear and, equally, the story of Milne’s troubled relationship with his son, and muse: the real Christopher Robin Milne.

Neither father nor son would go on to appreciate the impact of Winnie-the-Pooh upon their lives in later years. For Alan, the four books of the series would overwhelm and erase the memory of his other work; for Christopher, his fame from being ‘the real life Christopher Robin’ of the books would lead to bullying at school and resentment in adulthood.

The film explores the relationship between the pair – and with Christopher’s mother, Daphne, and nanny, Olive – alongside the effect that global success would have on each.

Who’s in it?

The cast for Goodbye Christopher Robin is absolutely as splendid as you might expect from a biopic of the Winnie-the-Pooh story.

Domhnall Gleeson takes a breather from his Star Wars mal-doings to play A. A. Milne – a return for the actor to the twentieth-century, following his part in 2015’s Brooklyn.

Milne’s wife, Daphne de Sélincourt, is realised by Margot Robbie. The Australian actress was last year seen having a riot in Suicide Squad, as Harley Quinn, and has most recently been sighted on the set of Mary Queen of Scots in full regalia as Queen Elizabeth I.

Interesting, this isn’t the only upcoming dalliance in classic children’s literature for the pair. Both will next year feature in Will Gluck’s live-action/CGI Peter Rabbit.

The young Christopher Robin is here played by newcomer Will Tilston, with Black Mirror and The Imitation Game‘s Alex Lawther taking the figure into his twenties.

No Country for Old Men and Brave-star Kelly Macdonald plays, nanny, Olive.

A pleasing supporting cast is made up of Phoebe Waller-Bridge (of Fleabag and the upcoming Han Solo spin-off), Stephen Campbell Moore, Geraldine Somerville, Nico Mirallegro, and Shaun Dingwall – to name a few.

Who’s made it?

Having begun his career in theatre and experimented in television, My Week With Marilyn and Woman in Gold director Simon Curtis helms Goodbye Christopher Robin.

Curtis’ script comes from Frank Cottrell-Boyce, writer of Danny Boyle’s London 2012 Olympic Opening Ceremony extravaganza, and Simon Vaughan, an expert on the subject having penned A Bear Named Winnie in 2004. That film, a TV feature, starred Michael Fassbender and told the story of the black bear cub who became a mascot for the Winnipeg section of the Canadian Army Veterinary Corps in 1914, before winding up in London Zoo and inspiring Pooh bear himself.

Goodbye Christopher Robin has BAFTA and RTS award-winning Production Designer: David Roger behind it, with music from Carter Burwell and cinematography by Viceroy House‘s Ben Smithard.

When’s it out?

The film is due for UK release on September 29, 2017.
