Steve James’ acclaimed new documentary The Interrupters about the Cease Fire community activist violence prevention volunteer organization in Chicago has been a genuine box office smash in its own city. The film, which officially concluded two week run at the Gene Siskel Film Center Thursday night is, according to today’s Chicago Tribune, the biggest box office success in the 40 year history of the Center.

The film, which was screened multiple times daily during its two week extended run, was sold out for every single screening and even extra screenings that were added to accommodate the crowds sold out in a flash as well.

Even additional screenings scheduled at the last minute for this weekend were sold out days ago, so you’re out of luck. Not surprisingly the Center will bring back the film for another extended run in October.

And additionally the Black Harvest Film Festival, which is also running concurrently with the The Interrupters at the Siskel Film Center and still has a week to go ending on Sept 1st, has also experienced huge attendance numbers and is set to break all previous attendance and box office records in the 17 year history of the festival.
