It only makes sense that superheroes would be used as icons for the 'Got Milk?' campaign from Body By Milk, and just in time for the release of The Dark Knight, Batman dons the milk mustache once again.

On the site for the campaign there is a new widget, wallpaper and icon, as well as an opportunity for one fan to win the chance to appear in a Batman comic book from DC Comics.

The Dark Knight opens on July 18, 2008, and stars Christian Bale, Heath Ledger, Morgan Freeman, Gary Oldman, Aaron Eckhart and Maggie Gylenhall.
