A four-story building was blown up and incinerated in Chicago today — at around 2 pm, or about six hours ago — for a scene in Chris Nolan‘s The Dark Knight, the latest Batman movie that’s been shooting in and around Chicago for the last few months. The demolition/ implosion/explosion happened at the old Brach’s Candy Factory in western Chicago. The building, vacant for several years, was dressed to look like “Gotham General Hospital,” blah, blah.

There is nothing in the world more boring that big explosions in action movies, but the live video footage taken today — here’s one angle, here’s another — is actually fairly cool. [Thanks for HE contributor and HollywoodChicago.com columnist Adam Fendelman for passing this along.]
