There’s been a lot of interesting meta-media showing up around the upcoming Batman film. They seem to have done a good job building the context of the world that the movies exist in.
This is an in-depth documentary about the life of Bruce Wayne as shown on Gotham Cable News. If anything it’s played almost too straight.
There’s tons of other fun goodies on the site as well, including web sites for Harvey Dent, and Gotham City Rail.
