Untitled Batman Begins Sequel went and got itself a title without telling me. A title and a (somewhat dull) teaser. The Dark Knight is due out on 18 July 2008. Mark your calendars. If you haven't seen Batman Begins yet, you should look into new real estate. Your current abode under that huge rock isn't helping you any.
Also in sequels that got names recently, Untitled Fourth Indiana Jones Movie is now Indiana Jones and the Kingdom of the Crystal Skull. I am cautiously intrigued.
