The world melted over little Miles when his Batkid wish came true [1] this past November, and now the tiny caped crusader has a crazy-cute movie of his big day in "Gotham City." For the thousands of people who couldn't get enough of the sweet superhero's story, the short film offers a behind-the-scenes look at Miles's moving experience. Batman, who accompanied Miles through San Francisco, shares some of the sweetest memories in the video, and his parents open up about how special the day was for the family. "Everybody was happy," Miles's dad says. "Everybody was smiling. Pretty heartwarming to see that — that everybody seemed to have a better day today because of Miles." Watch the touching video above.
