Star Wars: Where Science Meets Imagination opened on the 27th of October, 2005, at the Museum of Science in Boston, Massachusetts. George Lucas attended as guest of honor at the Grand Opening Gala, with Anthony Daniels serving as master of ceremonies.
The touring exhibition ran from October 2005 to March 2014, visiting 20 venues across the United States and Australia. Its final stop was The Tech Museum of Innovation in San Jose, California, where it closed on the 23rd of March, 2014.
The exhibition drew nearly three million visitors across its run in the United States and Australia.
The exhibition was developed over four years, beginning in 2002, by the Museum of Science, Boston, in collaboration with Lucasfilm Ltd. It was supported by the National Science Foundation under Grant No. 0307875, and presented nationally by Bose Corporation.
The exhibition included original props and costumes such as Darth Vader's helmet from Star Wars: Episode III - Revenge of the Sith, models of the X-wing and Millennium Falcon, costumes for characters including Mace Windu, Princess Leia, and the stormtroopers, and lightsabers belonging to Luke, Obi-Wan, Darth Maul, and Count Dooku. The Boba Fett costume was added on the 16th of January to replace the Chewbacca costume.
A companion book of the same name was published by National Geographic in October 2005, produced by LucasBooks and edited by the Boston Museum of Science. Anthony Daniels wrote its introduction, and a second edition was released in September 2006.
