Calling all Winnie-the-Pooh fans: there is now an origin story sure to tug on your heart strings.

Directed by Simon Curtis, Goodbye Christopher Robin explores the story of A. A. Milne and his son Christopher Robin, who inspired him to write the beloved classic Winnie-the-Pooh.

The trailer shows a mixture of misery and joy, as the family struggle towards a better life after the horrors of the First World War. Though Milne initially looks distant and exhausted, haunted by the war he has left behind, time with his son soon seems to heal him, transforming his life into a magical world where tales of 'Winnie-the-Pooh' are born.

The trailer depicts England in a beautifully nostalgic and magical way, reminding viewers of the world in which Milne, C. S. Lewis and countless other beloved English authors grew up. A country steeped in history, filled with nature and rife with possibilities, the very ingredients of great tales seem to surround our characters in the brief clips we have seen so far.

Starring Domhnall Gleeson and Margot Robbie, this happy family tale looks to be an uplifting story, as it shows how ordinary people overcome tragedy and suffering to embrace the beauty of life.

Both Domhnall Gleeson (A. A. Milne) and Will Tilston (eight year old Christopher Robin) appear to offer sweet and sensitive performances, portraying characters so vulnerable that it is impossible not to like them.

In a time of fast paced and overly brash films, this sweet and simple one looks to be a welcome change, reminding audiences that flashier isn’t always better.

Goodbye Christopher Robin is set for release in UK cinemas on September 29th 2017. Watch the trailer below.
