Evil Mary Poppins and the Mad Hatter will both be a part of Poohniverse: Monsters Assemble.

Directed by Rhys Frake-Waterfield, Poohniverse: Monsters Assemble is an upcoming horror crossover movie set in the same world, titled the Twisted Childhood Universe, as Winnie-the-Pooh: Blood and Honey and Winnie-the-Pooh: Blood and Honey 2.

Speaking with ComicBook, producer Scott Chambers spoke about what fans Poohniverse fans can expect from Monsters Assemble and how Mary Poppins, Peter Pan, and the Mad Hatter will serve as the three main antagonists of the film.

What did Scott Chambers say about Poohniverse: Monsters Assemble?

“I’ve not really spoken much about this yet, but Mary Poppins will be in it, and she’s going to be a kiddy snatcher as well,” Chambers said. “So I’m sure her and Peter Pan are going to get on like a house on fire. And then there’s also the Mad Hatter. I think those three are going to be the worst of the worst. We’ve introduced Peter and later down the line we will introduce the other two in their own films.”

There are several Twisted Childhood Universe movies that will be released before Poohniverse: Monsters Assemble, which is expected to arrive in 2025. Peter Pan’s Neverland Nightmare, which is directed by Chambers, arrives on January 13, 2025, while Bambi: The Reckoning and Pinocchio: Unstrung are also both scheduled for 2025.

Chambers further said of the Twisted Childhood Universe, “Every film will feel different, and [Peter Pan’s Neverland Nightmare] one is incredibly dark for a reason. I need you to feel a certain way about Peter Pan By the time we get to Poohniverse, because I need you to just not like him, I need you to be against him from the get-go. Because when he goes into the arena with, for example, Pooh, I need you to look at Pooh like He’s not all too bad.”
