It's been discussed here previously, but ReelChicago.com reports filming on the latest Batman will begin in July and continue through August. Cast includes Christian Bale in the lead role, with support from Liam Neeson, Katie Holmes and Michael Caine, to name a few. This isn't the first big budget coming our way, thanks to Brenda Sexton's hard work leading the Illinois Film Office. So far this year, producers of four major films - The Weatherman, Ocean's 12, Batman, and Ice Harvest - have sealed deals to film in Chicago.
