There’s a guy that let me know about his Kickstarter project to get funding for a fan-made film having to do with the events between The Dark Knight and The Dark Knight Rises. The goal, apparently, is to make a movie in the Nolan universe that shows the villains we won’t see: Riddler, Mr. Zsasz (seen briefly in Batman Begins) and others.
So if you have the inclination and want to help someone make something that might be a lot of fun to watch…head on over and kick in a few bucks. They could use the help, and it seems pretty interesting. I have no idea about Warner Bros. or DC or anything like that, but I don’t know how a fan film made on a worthwhile scale could hurt anything when Paramount lets things like that Star Trek fan series exist.
