Warner Bros and Walmart have teamed up to promote the DVD release of The Dark Night Rises by creating a Batmobile app that allows users to picture themselves at the wheel of the iconic vehicle.

The basic iOS app features the Batmobile Tumbler from The Dark Night Rises; users can unlock four further Batmobiles by locating special marker images in Walmart stores.

The Dark Night Rises will be released on DVD, Blu-ray and download on December 4.
