Winnie the Pooh and his adventures in the 100 Acre Wood have brought joy and comfort to generations. The new film Goodbye Christopher Robin dramatizes how those stories were a healing response to trauma and pain for its creator A.A. Milne.

After fighting in the trenches of World War I, Milne sought rural retreat with his family to focus on his writing. As this new movie portrays, his literary pursuit lead somewhere he wasn’t expecting, one that impacted the world.

Domhnall Gleeson stars as A.A. Milne, Will Tilston as his son Christopher Robin (yes, the namesake of Pooh’s human friend), Margot Robbie as Milne’s wife Daphne, and Kelly MacDonald playing Christopher Robin’s nanny, Olive.

Bumped up from its November release, Goodbye Christopher Robin now opens on October 13th, 2017.
