If you’ve ever wondered about the backstory behind all the fine print on containers of E.H. Bronner’s peppermint soap, Sara Lamm’s 2006 documentary tells you everything you’d want to know and then some. And the story being told is certainly a singular one. Bronner, a German Jewish immigrant and onetime mental patient, abandoned his children to produce and sell his soap and spread his ideas about humanitarianism. Today his son Ralph qualifies as one of his most ardent disciples. For better and for worse, this is a movie that raises almost as many questions as it answers. 88 min. (JR)
