Buried a ways down in today's Reel Chicago blog is an item of particular interest: The next "Batman" movie, "The Dark Knight Rises," is set to be filmed in Detroit, as well as New Orleans and the U.K. (It had originally been planned for Chicago.)

As we all know, when the movie industry has plans for "Detroit," they often extend to the greater Ann Arbor area. And while Detroit proper does seem like a much more natural Gotham City than our fair burg, there may yet be potential. (Maybe ... new Gov. Rick Snyder's house standing in for Wayne Manor? Hmm?)
