Even though they said they weren't gonna pick it up, the folks at Exploris are bending their educational mission to welcome the most recent George Lucas production, Star Wars Episode II--Attack of the Clones. This is no qualified welcome either: They're going all out--they're inviting Peter Mayhew (pictured), aka Chewbacca, to grace the premiere weekend. And they've got enough other Star Wars-related activities going on that you might just miss the "IMAX experience" altogether if you don't pay attention. These activities include live light saber dueling, autographs with Mr. Mayhew, the premiere of the fanzine Star Wars Bantha Tracks and rounds of Star Wars trivia games--oh, and complete grown-ups dressed up like your favorite characters. The outsized film plans to stick around for a while, based on events Exploris has scheduled later this year and into next year--Star Wars characters in Raleigh's holiday parade, Star Wars Day in January, and Star Wars customizable card game demonstrations in November, December and January. Use the force at the premiere this Friday from 3:30 to 10 p.m. and again from 5 to 10 p.m. on Saturday. Call 834-4040 for tickets.
