The Celebrations date back to the release of the first prequel in the "Star Wars" saga - 1999′s "Star Wars: Episode I - The Phantom Menace." The first convention took place in Denver just weeks before "Episode I" opened; subsequent events took place in Indianapolis, Ind.; Orlando, Fla.; and overseas, in Japan, England and Germany.

Franklin also confirmed the involvement of prominent fan groups, including the famous 501st Legion of costumed fans who dress like Imperial stormtroopers.
