Margot Robbie is helping to bring the story of Winnie the Pooh to life in the trailer for her upcoming movie Goodbye Christopher Robin. The film tells the tale of author A.A. Milne (played by Domhnall Gleeson) as he crafts the story of Winnie the Pooh with the help of his son Christopher Robin (played by the incredibly adorable Will Tilston). The Wolf of Wall Street star plays Daphne de Sélincourt Milne, wife and mother.

Sharing the trailer to her Instagram this week, Robbie said of the film: "Had the most magical time shooting this. Trust me, you don't want to miss #GoodbyeChristopherRobin"

The trailer sees Robbie using a quaint (and very convincing) British accent, and brings light to the struggles that A.A. Milne had with post-traumatic stress disorder following his time serving as Captain in World War 1. Christopher Robin says to Milne; "I'd really like if you wrote a book for me, I'd definitely read it" and so the story of Winnie the Pooh and the Hundred Acre Woods begins.

The trailer brings back all the childhood nostalgia, and something tells us it will also be a little bit of a tear jerker. Watch it below.
