A new documentary was announced at Disney’s D23 Expo (read all of our coverage here) from filmmaker Leslie Iwerks, who’s previous credits include The Pixar Story, Industrial Light & Magic: Creating the Impossible, and Recycled Life, a documentary short that scored her an Academy Award nomination. Iwerks comes from Disney royalty, the daughter of Disney Legend Don Iwerks and granddaughter to Ub Iwerks, the co-creator of Mickey Mouse and Oswalt the Lucky Rabbit, and recipient of that now famous letter from ol’ Walt himself back in 1924 excitedly talking about what was going on at the time and Ub’s move out west.

Iwerks’ latest project is not yet titled, but will tell the story Walt Disney‘s legendary group of magic makers, The Imagineers. The Imagineers are a group of exceptionally talented people, the wizards behind the curtain if you will, who brainstorm and create the things that make Disney theme parks and attractions so special. The documentary isn’t to be released until 2016 (that’s right, you have to wait longer for this than you do Star Wars Episode VII), but a trailer for the doc has been released and it looks like a fascinating peek behind said curtain.

You can check out the trailer for Iwerks’ Imagineering documentary below.

The Journey Into Imagineering exhibit at this year’s D23 Expo in Anaheim, CA, takes attendees into the various components of Walt Disney Imagineering. Past, present and future are all covered inside this massive venue, flooding with artistry and the artists who have made them a reality. Each area of the exhibit features Imagineers, many of whom have worked on projects, including the recent Disney California Adventure theme park expansion.

Check out our photo gallery here below from the exhibit, which includes perhaps the “geekiest” touches one could appreciate: hints of Marvel, Avatar, and Star Wars making their way to the Walt Disney Parks and Resorts!

Captain America greeted his legions of fans in the Marvel Academy-themed space. The concept art on the walls depict a future kids club area of the Disney Magic ship aboard Disney Cruise Line. “The First Avenger” will be appearing soon, and made his inaugural Disney experience at D23 Expo. Salute to the Captain!
