The movie stars our own gal Margot Robbie, and it will show the perspective of Christopher as a young boy. However it's really, really dark...
His father, who is a writer, suffers from PTSD from the war, and sets out to write the famous Winnie The Pooh stories while suffering from flashbacks to his time in the war.
Watch the trailer below, and like we said, we warned you it was sad!
