JT LeRoy – whose mussed hair, punk band T-shirt and unnerved, potent expression captivated writers at first introduction – was in many senses a puppet, whose various aspects relied on consistent control: constant twitches of Geppetto’s strings. Author: The JT LeRoy Story (15, 111 mins, ★★★★) tells of how an American female writer pretends that her Southern Gothic fiction has been written by a teenage boy whose purported past, roiled by abuse, prostitution and lunatic internment, has informed the work.
