This is a really good reenactment of the opening of BTAS. I appreciate their use of 3D models of the Batmobile and the Gotham City landscape together with using real actors.

It makes me wish for a live action BTAS-style Batman film.
Here is a BTS video of how these guys filmed the whole sequence. Man, I'd hate to be one of those people living in those apartments and hearing a thud on the rooftop every time someone is trying to recite Batman jumping properly.

And here is another video of the fans making the Batsuit. Too bad the actor's head couldn't fit the Keaton cowl, it would've made the video even better. :D
