‘Concrete Jungle Gym’ traces life of Bob Cassilly, from City Museum to Cementland

The documentary "Concrete Jungle Gym" chronicles the brilliant life and legacy of Bob Cassilly and the creation of the City Museum. Premiering Nov. 10 at the St. Louis International Film Festival, the film draws on decades of footage to create an unusually intimate portrait of an artist driven to create new art from the demolished pieces of the city around him, and who often found himself at odds with St. Louis authorities. We talk with the film's creators, Mike Gualdoni and Zach White.
