Hollywood Studios Cast Members Sign a Beam for the Monsters, Inc. Door Coaster
Cast members at Disney's Hollywood Studios have signed a black steel beam that will become part of the Monsters, Inc. door coaster in Monstropolis. Monstropolis opens in phases starting in 2027, but Disney has not dated the coaster.

Cast members at Disney's Hollywood Studios have signed a steel beam that will become part of the Monsters, Inc. door coaster in Monstropolis. The signed beam gives the people who run the park a permanent place inside the land's headliner, which will be the first suspended coaster in a Disney park.

The Buzz
Monstropolis is the biggest project under way at Hollywood Studios, and a beam signing is one of the few construction moments Disney shares with photos. It is also a sign the coaster's structure is far enough along to take finished steel.
Signatures and Monsters, Inc. doors cover the beam
Photos from the signing show a black beam covered from end to end in cast member names.
- White signatures. Names in white run the full length of the black beam, some in neat print and others in big looping scrawl.
- Door stickers. Die-cut stickers shaped like the film's doors, with Sulley and Mike peeking around the frame, are mixed in among the names.
- Names inside doors. Cast members wrote their names in the open door space on those stickers.
- Costumed selfies. Cast members in costume took selfies in front of the beam.
Disney framed the signing as a milestone for the land, and for the cast members who will one day work there.
"The beam signing gives cast members the opportunity to leave a lasting mark on the future of Disney's Hollywood Studios," Disney said.
A Walt Disney World tradition for big projects
Beam signings have marked several recent Walt Disney World headliners while they were still under construction.
- Encanto in January. Disney's Animal Kingdom cast members signed a steel beam for the upcoming Encanto attraction in January 2026.
- Galaxy's Edge in 2017. Hollywood Studios cast members signed the beam that formed the highest point of Star Wars: Galaxy's Edge.
- Busy October. This month also brought the first entrance bricks in Monstropolis and themed paint on Archie's Scare Pig Pizza, one of the land's restaurants.
Coaster opening date still unannounced
The land opens in phases from 2027, but Disney has not dated the coaster itself.
- Track since June. The first piece of track went in during June, connected to support steel inside the show building.
- More track by October. Aerial photos this month showed more track inside and blue walls covering part of the building.
- Vertical lift. A vertical lift will raise riders into the air, just like the moving doors in the Monsters, Inc. film.
- First wave. The Glob Theater, Archie's Scare Pig Pizza, Harryhausen's and the Scareporium lead the phased opening of Monstropolis starting in 2027.
Our take. Anyone planning a 2027 Hollywood Studios trip should count on the first wave of Monstropolis venues, not the door coaster, since Disney has given the ride no opening date.
