STAR WARS SPECTACULAR
On January 1, 2007, denizens of a galaxy far, far away will march down the streets of Pasadena, California, in a one-of-a-kind "Star Wars Spectacular" during the 118th Pasadena Tournament of Roses Parade(R).
More than 350 Star Wars characters, including stormtroopers, Imperial officers, Ewoks and Darth Vader himself will entertain the nearly one million people expected to line the streets of Pasadena to see the Parade in person and the tens of millions of more around the world who tune in via multiple television broadcasts.
The massive Imperial stormtrooper contingent will comprise members of the international 501st Legion, a costuming and volunteer organization made up of Star Wars fans. Some 200 stormtroopers from more than 20 countries will participate in the Tournament of Roses Parade, showcasing the emblems and colors of their local garrisons.
"During the global premiere of Star Wars: Episode III last May, George Lucas was deeply impressed by the presence of 501st Legion members around the globe, and we wanted to honor them for their loyal support of Star Wars and their global philanthropy," said Tom Warner, Senior Director of Marketing for Lucasfilm Ltd. Members of the 501st regularly volunteer their time to support local charitable efforts.
Providing musical entertainment in the "Star Wars Spectacular" will be the renowned Grambling State University Tiger Marching Band.
In keeping with this year's Parade theme "Our Good Nature," the "Star Wars Spectacular" will feature the Ewoks, residents of the forest moon of Endor, who will ride on a float showcasing their planet's unique environment with a plea to "Save the Trees."
The celebration of Star Wars -- which coincides with the start of the 30th anniversary of the epic, six-episode adventure -- will also showcase a float that depicts the romantic beauty of Naboo, the garden planet of the Star Wars galaxy.
"Being part of a grand tradition like the Rose Parade is a fantastic way to kick off this milestone year," Warner said. Over Memorial Day Weekend 2007, a large fan convention, Star Wars Celebration IV, is expected to attract more than 30,000 worldwide fans to the Los Angeles Convention Center.
