Watch This Behind the Scenes Clip of The Dark Knight's Bat

By Peter Ha on at

While you were watching Nolan's third and final Dark Knight flick, did you wonder how in the hell they got the Bat to do all of its hovering, darting and intimidating? Sure you did!

With the movie about to drop on DVD and Blu-ray next month, we're getting some fun teasers ahead of launch, like this sweet behind the scenes look at the updated Batwing.

Inspired by an Osprey prop jet, Harrier jump jet and Apache attack helicopter, the Bat weighs roughly 3000 pounds and is 17 feet wide and 30 feet in length. Didn't know this but might explain the ending but the Bat's rotor blades operates much cooler than conventional jets giving it a smaller heat signature. And here's a fun fact about the Bat - it's made of mostly styrofoam, according to a friend who worked on the film while it was shooting in New York.

For those that opt for the Blu-ray edition, you might want to download the "The Dark Knight Rises" app for iOS (iPhone, iPad) or Android (not yet available) as it'll act as a second screen with oodles of info like Gotham City maps and other neat extras while you watch. The epic ending will be available on December 4.
