Two former Disney writers are urging Pixar to revisit a long-shelved sequel to MONSTERS, INC., a family favorite that first brought Mike, Sulley and little Boo to theaters in 2001.
“We stand by that script, we’re very proud of it,” writer Rob Muir said of the unmade project, as reported by ScreenRant.
Muir and fellow writer Bob Hilgenberg developed MONSTERS, INC. 2: LOST IN SCARADISE more than two decades ago, during the complicated stretch before Disney acquired Pixar. Their pitch reportedly would have sent Mike toward marriage, elevated Sulley at Monsters, Incorporated and brought an older Boo back into their world.
That last detail gives the abandoned idea its emotional pull. Pixar’s own MONSTERS, INC. page still centers the friendship that grew when Sulley learned that love and laughter carried more power than a child’s scream, a fitting heart for the original movie.
The sequel never moved forward. According to the report, Hilgenberg and Muir worked on the project while Disney considered making follow-ups through its then-planned Circle 7 animation unit, but the plan changed after Disney’s Pixar acquisition and the writers’ version was put aside.
Instead, audiences later got MONSTERS UNIVERSITY, the 2013 prequel that explored how the mismatched pair met and became friends. Pixar describes MONSTERS UNIVERSITY as the story of two future friends who initially could not stand each other, a reminder that the franchise has always had room for both comic chaos and genuine character growth.
There is no official word from Pixar that Hilgenberg and Muir’s screenplay will return, and fans should treat their plea as a hope rather than an announcement. Still, the writers believe their story has not lost its spark. “Our goal was, when somebody read the script, to not know if we were influenced by Pixar or not,” Muir said, describing a script they wanted to feel at home beside the studio’s family-centered storytelling.
That confidence is understandable when the characters have endured for so long. MONSTERS, INC. works because its wild premise finally turns toward compassion: Sulley and Mike discover that protecting a frightened child matters more than keeping an old system running.
A future sequel would need to honor that moral center, not simply recycle familiar faces. The prospect of an older Boo could offer a fresh way to revisit the courage and care that made the original movie memorable for parents and children alike.
For parents who grew up with the original movie, that idea lands on more than nostalgia. Disney’s D23 archive notes that MONSTERS, INC. arrived Nov. 2, 2001, with John Goodman as Sulley and Billy Crystal as Mike, and it remains one of Pixar’s most recognizable stories about friendship, courage and choosing care over fear.
Whether Pixar ever opens that door again remains up to the studio. For now, Hilgenberg and Muir’s call gives fans a glimpse of a sequel that might have been — and of why Boo, Mike and Sulley still matter to families who loved their first adventure.
