There are a lot of amazing things about Christopher Nolan's "Inception," one of which is undoubtedly the many insane sets throughout the film. One of the most striking is a towering Japanese fortress that appears at the beginning of the movie, setting the stage for a topsy-turvy ride through the imagination.

With the DVD and Blu-ray out this week, we wanted to give you a taste of the very interesting behind-the-scenes featurettes. To that end, we have a clip of Nolan's crew discussing the designing of the castle and how it was conceived. Check it out below.
