WarnerMedia Kids and Family announced plans to expand its partnership with children’s book author, illustrator and playwright Mo Willems — including a slate of originals for HBO Max and Cartoon Network. With Stampede Ventures as producing partner, Willems signed a multi-year deal with WarnerMedia Kids and Family to create live-action “Storytime Specials,” as well as multiple animated and live-action series based on his children’s books. “Mo Willems and The Storytime All-Stars Present: Don’t Let the Pigeon Do Storytime!” and “Mo Willems Story Time Shorts!” are now available to stream on HBO Max.
