The Chicago Tribune has reported that Warner Bros. will be filming The Dark Knight in Chicago next year:

For 2007, Warner Bros. already has committed to shooting a good portion of the next Batman flick, starring Christian Bale, in the Windy City.

The Dark Knight arrives in theatres on June 18th, 2008, where Batman and Gordon find alliance with a newly appointed DA Harvey Dent to stop a vicious killer with a warped sense of humor known only as The Joker, a threat to both the good, and the evil of Gotham City.
