Fantasmic! is a nighttime show at Disneyland in the Disneyland Resort, Disney's Hollywood Studios in Walt Disney World, and Tokyo DisneySea in Tokyo Disney Resort, that features fireworks, live actors, water effects, pyrotechnics, lasers, music, audio-animatronics, decorated boat floats, and mist screen projections. The narrative structure of Fantasmic!—although varying differently in set pieces in all three versions—centers on a voyage through Mickey Mouse's imagination that culminates in a battle against the Disney Villains.
Fantasmic! originated at Disneyland in 1992 after Walt Disney Creative Entertainment was asked to create a nighttime spectacular involving water and fireworks to reinvigorate the space in front of the Rivers of America. The area was reworked, including terracing the walkways to accommodate viewing and modifying part of Tom Sawyer Island to allow the show's staged live action segments. The producers employed the resources of Walt Disney Feature Animation and Walt Disney Imagineering.
A second version, featuring new scenes, debuted at Disney-MGM Studios in 1998 and a third version debuted at Tokyo DisneySea in 2011, replacing BraviSEAmo!
