Monsters, Inc. 3 (2025) brings back the beloved duo of John Goodman and Billy Crystal as Sulley and Mike in a new adventure that reintroduces audiences to the enchanting, laughter-fueled world of Monstropolis. Set years after Monsters University and Monsters, Inc., this third installment sees the monster world evolving, with laugh power now firmly established as Monstropolis’ main energy source. However, new challenges await as changes in the human world lead to unforeseen effects on the monster community.
The teaser opens with Mike and Sulley running the Laugh Floor, where laughter has become the heart of Monstropolis. But things take a turn when they discover that children’s reactions are changing—they’re growing up faster, and laughter is becoming harder to generate. Faced with dwindling laugh energy and an uncertain future, Mike and Sulley set out on an adventure to understand the changing relationship between children and monsters. Their quest takes them into new, unexplored realms of the human world, where they must rediscover what makes children laugh and rekindle the bond that fuels their city.
Familiar faces make a return, including Celia (Jennifer Tilly), Roz, and fan-favorite Boo, who’s now a teenager grappling with the memories of her past encounter with the monster world. As Boo reconnects with her childhood friends, she becomes an essential part of helping Mike and Sulley reestablish laughter power, bridging the gap between two worlds once again.
The animation promises to be cutting-edge, blending Pixar’s signature charm with a fresh take on Monstropolis, and introducing new characters from both the monster and human worlds who add to the film’s humor and heart. With its reported budget of $200 million, Monsters, Inc. 3 promises a stunning visual experience, nostalgic nods for longtime fans, and a story filled with laughter, friendship, and innovation.
Directed by a Pixar veteran known for balancing humor and emotion, Monsters, Inc. 3 brings the magic of Monstropolis to a new generation, exploring timeless themes of friendship and change. Sulley and Mike’s adventure will remind audiences that, no matter the challenges, laughter truly is the most powerful force of all.
