Fans who have been eagerly awaiting the July 20 release of Warner Bros. Pictures’ and Legendary Pictures’ “The Dark Knight Rises” will have an opportunity to get a firsthand look at the Tumbler and the Bat-Pod, which are rolling out on a coast-to-coast tour, sponsored by Mountain Dew and IMAX. Both the Tumbler and the Bat-Pod have served as high-powered modes of transportation for Batman in Christopher Nolan’s earlier blockbusters—with the Tumbler first appearing in “Batman Begins,” and the Bat-Pod being introduced in “The Dark Knight.”  They will both be featured in different ways in the hugely anticipated finale to the director’s Batman trilogy, “The Dark Knight Rises.”
