Warner Bros. has released a 13-minute video clip from "The Dark Knight Rises." That would be plenty of time for spoilers, but instead this mini-feature has director Chris Nolan talking about the intent behind the film and cast members Christian Bale, Anne Hathaway, Joseph Gordon-Levitt, Michael Caine and Morgan Freeman discussing how they worked to bring Nolan's vision to life. If this sounds too chatty, don't worry. There are plenty of looks at a profoundly dark and gritty Gotham, the relentless action, sprawling sets and crashing visual effects. And after this clip, you'll know it isn't CGI. It opens July 20.
