Working on John Boorman’s film of Deliverance, his father barred from the set for disturbing the actors, Christopher Dickey was asked to stand in for Ned Beatty while Boorman rehearsed the film’s most infamous scene. In it, the centerpiece of James Dickey’s tale of suburban devolution, a grotesque mountain man sodomizes Beatty’s character. Bent over a rotting log, Christopher resigned himself to the humiliation. Described in Summer of Deliverance, the episode is only one of the many times Christopher got fucked for something his father literary giant, macho poet, and compulsive liar had done. Simply told, the memoir manages something remarkable: It trumps Dickey’s novel because it’s not merely a fictional story of survival, but a real one of a son surviving his father’s destructive influence. Find out just how much thicker blood is when Christopher reads from Summer at 7 p.m. at Politics & Prose, 5015 Connecticut Ave. NW. Free. (202) 364-1919. (Roberto Aguirre-Sacasa)
