Glendale, Calif., Nov. 29, 2007 - Ten time Emmy®-award winning composer Bruce Broughton conducted a 63-piece orchestra and 24-voice choir for a new musical score for Spaceship Earth at Walt Disney World Resort. Walt Disney Imagineers have been re-imagining the iconic Epcot attraction since earlier this year, and have added new show scenes to the attraction's story line, along with new lighting effects, costumes, set decoration, and a new narrator - Academy Award®-winning, English actress Dame Judi Dench.
For the musical score, each scene was infused with musical styles and instruments appropriate to the time period, which was not an easy task according to Walt Disney Imagineering senior show producer Bob Zalk. "To have that score transition smoothly as vehicles travel from one time period to the next is extremely difficult," he said. "The first time we rode through the attraction accompanied by that music, we were amazed."
Spaceship Earth has been on hiatus since earlier this year, and is expected to re-open in December for sneak previews. When it re-opens, Spaceship Earth will combine the magic of the iconic attraction's time-travel adventure into the past with a new finale and post-show, presented by Siemens, which provides guests the opportunity to imagine their futures. Guests discover how each generation of mankind has invented the future for the next generation, and how the spirit of innovation has moved people from the caves to the cosmos.
