'Goodbye Christopher Robin' will center on the relationship between Milne and his son, who acted as the inspiration for the imaginative Christopher Robin.

Domhnall Gleeson is in early talks to play Winnie the Pooh creator A.A. Milne in Goodbye Christopher Robin.

The movie will center on the strained relationship between Milne and his son, who served as the inspiration for Christopher Robin.  Milne based the honey-loving Pooh Bear on his son's beloved stuffed teddy bear.

Damian Jones and Steve Christian are producing the film, which is being developed by Pathe.

Gleeson is coming off a big 2015. He starred in the critically acclaimed indie Ex Machina, opposite Oscar Isaac, had a leading role in Oscar-fodder The Revenant and also portrayed General Hux in Star Wars: The Force Awakens.

Recently, the Harry Potter actor was cast in the National Lampoon origin story A Futile and Stupid Gesture.

Gleeson is repped by Paradigm and Ireland's The Agency.
