Fantasmic is a multi-million dollar production with a cast, crew, and support personnel of 70+ people on the island during show. Yes, the bridge is retracted during show, thus turning the mountain into an island. There are also 5 lifts, pyrotechnics, lasers, watercraft, fall hazards, a moat full of water, and a mechanical dragon. The show is blocked/choreographed so that all 70+ people can perform the show safely around all of these potential hazards. Add in multiple casts/crews and you have a multi-month rehearsal process. Once the cast and crew are on the island, they are "on stage" the entire time. There are no dressing rooms or places to chill during show. There is almost constant movement onstage and offstage and it works like clockwork. This takes time.
