The city of San Francisco was transformed into "Gotham City," with an army of volunteers and even Major League Baseball team the San Francisco Giants working together to make Miles' wish come true as he whisked around town with Batman catching villains like the Joker and saving damsels in distress to the supportive cheers of thousands of onlookers.

As the Batkid phenomenon grew into such a massive collaborative endeavor, more luminaries have come out wanting to contribute to the project to make the moment as special as possible for Miles, including renowned composer Hans Zimmer, the man responsible for the music behind The Dark Knight movie trilogy who has written a special theme song specifically for Batkid.
