Margot Robbie is in early negotiations to co-star with Domhnall Gleeson in Simon Curtis’ “Goodbye Christopher Robin.”

Curtis will direct the pic that revolves around “Winnie the Pooh” creator A.A. Milne and the relationship between him and his son Robin. Robin, who initially had a difficult relationship with his father, served as the inspiration for the character of Christopher Robin.

Pooh was named after Robin’s teddy bear. The real Robin’s toys also lent their names to other Winnie the Pooh characters such as Tigger, Eeyore and Piglet.

While negotiations have just started, if a deal were to close, Robbie would play Milne’s wife.

Damian Jones is producing along with former Pinewood Pictures head Steve Christian. Pathe developed the project, which will go through Jones’ first-look production pact with Fox Searchlight.

Robbie has a busy summer ahead of her, with two major tentpoles set to premiere. In July, she will play Jane in “Legend of Tarzan” for Warner Bros. and in August will play Harley Quinn in WB’s “Suicide Squad.”

Anticipation for her “Suicide Squad” role is so fervent that Warner Bros. has already begun developing a Harley Quinn spinoff film starring Robbie. She also recently co-starred in “Whiskey Tango Foxtrot.“

She is repped by CAA, Management 360 and Aran Michael Management.
