One of the most prolific art forgers in US history, Mark Landis has duped over 40 American museums with an impressive array of ingeniously crafted fakes, ranging from 16th-century religious paintings to illustrations by Dr Seuss. For reasons that this film explores with delicacy and precision, Landis, long since diagnosed schizophrenic, has never made a cent from his nefarious pursuit. Rolling up at august institutions of art, culture and religion posing as a bereft relative or a Jesuit priest bearing inherited gifts, he’s been an honoured guest. Once discovered and widely reported, his ‘philanthropic binges’ (as he describes them) have proven horribly embarrassing to art world professionals – several of whom account for their gulling with a modicum of dignity in this film. But two of them appear permanently shaken. With no legal redress to alleviate their insecurity – giving away forged art is not a crime – their drive to curtail and contain him provides this documentary with a very suggestive counter-narrative. Sheepish, wry, his voice a whisper, his chit-chat a cut-and-paste of juicy lines from the classic movie channel, Landis may forever elude them.
