As expansive as the great chef-inventor Homaro Cantu was, he could also be maddeningly secretive, particularly about the seemingly limitless number of fantastical, world-changing projects he was embroiled in at any given time. This documentary by Brett A. Schwartz provides some insight into Cantu’s mystifying and appalling suicide in April 2015, but mainly it charts his journey from homeless youth to world-renowned modernist chef with a thousand ideas for making the world better. Cantu’s character as tech-obsessed idealist certainly comes across, though not the madcap sense of humor that propelled his busy kitchens.
