In another Gleeson/Robbie collab, our scene-stealing queen plays the wife of Winnie the Pooh author A.A. Milne and the mother of Christopher Robin (yes, the cartoon character is based on Milne’s real son). Far from a typical wife/mom role, Margot plays the London socialite with the perfect mix of pragmatic strength and energetic tenderness. Plus, at points the actor playing her son is only five years younger than Robbie, so kudos for making that believable.
