This cult favorite began as Francis Ford Coppola's UCLA thesis, ending up with a professional cast and nationwide release. Teen Peter Kastner undergoes his coming-of-age rites when, urged on by dad Rip Torn, he strikes out on own and moves to NYC. Every person Kastner meets is an eccentric's eccentric, from landlady Julie Harris to cop Dolph Sweet. Kastner's new friend
Tony Bill, who works at the New York Public Library and accumulates pornography on side, introduces the boy to sex and drugs.

Adapted from a novel by David Benedictus,
Big Boy is afflicted with usual youthful film-class fervor, crammed full of showoffish cinematic tricks that Coppola would eventually outgrow.
