Bud Cort is a poor little rich boy who fakes suicides to attract his mother’s attention; Ruth Gordon is a life-loving septuagenarian who steals cars and poses in the nude. Hal Ashby’s 1972 cult film may be simpleminded, but it’s fairly inoffensive, at least until Ashby lingers over the concentration-camp serial number tattooed on Gordon’s arm. Some things are beyond the reach of whimsy.
