Query: Why Did MacNaughton Quit Acting ?

Robert MacNaughton brings considerable charm and integrity to the role of a nerdy, geeky teen with issues. This is probably the best portrayal of a teenager in film prior to River Phoenix's brilliant performance in RUNNING ON EMPTY. (With which this film shares a certain similarity of subject matter.)In a way, he carries the whole film.Hope Lange and Don Murray are not given much to do as MacNaughton's parents, and their acting is somewhat cliched. Robert Wagner as a psychiatrist who may or may not be in sympathy with the boy, is somewhat better.There is a fine score by Jonathan Tunick, and the Vermont and Massachusetts locations are gorgeous.
