Comic geeks have Comic-Con, gamers have E3, and now Disney fans have their own personal mecca: the D23 Expo. Launched in 2009, D23 took 2010 off but came roaring back last weekend (Aug. 19-21) at the Anaheim Convention Center. Billed as “the ultimate Disney fan event,” D23 gave attendees an exclusive sneak peek at the company’s upcoming movies (including The Avengers and John Carter) and theme-park attractions. Also featured was the Treasures of the Walt Disney Archives, a museum that displayed costumes and props from such films and shows as Pirates of the Caribbean, Alice in Wonderland, Who Framed Roger Rabbit, and Lost. And perhaps most alluring of all for Disney nuts was the Collectors Forum — a gigantic marketplace of Disney-themed merchandise from pricey paintings to vintage figurines to life-sized animatronic robots. If you wanted a Yahtzee game in which the dice cup has been replaced by the skull of Jack Skellington, D23 had it.

To help make sense of it all, EW talked to Steven Clark, Disney’s head of D23. Click through to hear his thoughts on this year’s event and to see footage from the Expo floor:
