The film centers around a grown-up Christopher Robin trying to find his inner child after getting too absorbed in his work. (So, basically "Hook," but with Winnie the Pooh.)
Pooh most recently appeared on screen in 2011's "Winnie the Pooh," although sources say that this film will focus on Robin as opposed to the beloved bear.
The fantasy film is supposed to "lean towards magical realism in service to a heartwarming story," according to the report.
The film is produced by Brigham Taylor ("The Jungle Book") and written by Alex Ross Perry ("Listen Up Philip").
Another Christopher Robin film, "Goodbye Christopher Robin," starring Margot Robbie and Domnhall Gleeson, is currently being produced by Fox Searchlight.
