No doubt many of you grew up reading A.A. Milne's Winnie the Pooh tales – but do you know the true story behind their creation?
Well that's now the subject of nostalgic and affectionate drama Goodbye Christopher Robin, one exploring the author's close relationship with his young son Robin, and how this inspired the classic storybook characters.
Not only does the movie have a fascinating true story on its side. The cast is also superb: Brooklyn and Ex Machina star Domhnall Gleeson plays Milne with Suicide Squad's Margot Robbie as his wife Daphne and Trainspotting's Kelly Macdonald as their nanny, Olive.
Directed by My Week With Marilyn filmmaker Simon Curtis, the movie arrives on 29th September. Check out the first trailer below.
