summer of 42

Summer of '42 is a 1971 American "coming-of-age" drama film based on the memoirs of screenwriter Herman Raucher. It tells the story of Raucher as a boy, in his early teens on his 1942 summer vacation on Nantucket Island, off the coast of New England, who embarked on a one-sided romance with a woman, Dorothy, whose husband had gone off to fight in World War II.

The film was directed by Robert Mulligan, and starred Gary Grimes as Hermie, Jerry Houser as his best friend Oscy, Oliver Conant as their nerdy young friend Benjie, Jennifer O'Neill as Hermie's mysterious love interest, and Katherine Allentuck and Christopher Norris as a pair of girls whom Hermie and Oscy attempt to seduce. Mulligan also has an uncredited role as the voice of the adult Hermie. Maureen Stapleton (Allentuck's real life mother) also appears in a small, uncredited voice role (calling after Hermie as he leaves the house in an early scene).

Raucher's novelization of his screenplay was released prior to the film's release and became a runaway bestseller, to the point that audiences lost sight of the fact that the book was based on the film and not vice-versa. Though a pop culture phenomenon in the first half of the 1970s, the novelization went out of print and slipped into obscurity throughout the next two decades until a Broadway adaptation in 2001 brought it back into the public light and prompted Barnes & Noble to acquire the publishing rights to the book.
