Chris Hegedus and D. A. Pennebaker, two exceptionally celebrated and accomplished documentary filmmakers (their respective resumes include such influential classics as The War Room and Don’t Look Back), combined for this account of the legal fight to free chimpanzees from their cages – not by storming zoos or research facilities, but by going to court, and asking the U.S. justice system to consider “the personhood of non-human animals.” The attorneys make a compelling argument – and court is an unprecedented case to make it.
