Domhnall Gleeson to play Pooh's creator AA Milne in Goodbye Christopher Robin
Winnie-the-Pooh creator AA Milne will be played by Domhnall Gleeson in a new movie, with Margot Robbie as his wife.
The Revenant actor will play the beloved children's author in Goodbye Christopher Robin.
Robbie, who stars in Suicide Squad and The Wolf Of Wall Street, will play Milne's wife Daphne in the Simon Curtis-directed film from Fox Searchlight.
The movie tells the story of Milne and his son, the real-life Christopher Robin, whose toys inspired the tales about Winnie-the-Pooh.
The movie will show Christopher, his nanny Olive and his parents as they are swept up in the international success of the books in the aftermath of the First World War.
But what impact will this new-found fame have on the Milne family?
Goodbye Christopher Robin is written by Frank Cottrell Boyce and Simon Vaughan.
Curtis said: "I am delighted to be collaborating with Frank Cottrell Boyce to tell the remarkable and poignant story of the family behind the creation of Winnie the Pooh.
"We are assembling a wonderful cast, headed by two actors I am longing to work with - Domhnall Gleeson and Margot Robbie."
