Two fine-arts documentaries in one. Photographer/collector John Maloof’s profile of the enigmatic Ms. Maier – a nanny whose spare-time photos of street scenes and people have been compared to those of Robert Frank and Henri Cartier-Bresson – covers both Maloof’s “discovery” of the late Maier’s heretofore-unseen oeuvre in trunks and boxes, plus the reactions of her former employers, who are almost as eccentric as Maier was reputed to be. A good introduction to Maier’s work, a cavalcade of curious city sights with special emphasis on the downtrodden and unlucky. Written and directed by Maloof and Charlie Siskel (83 min.).
