Adapted by Chris Columbus from a story by Steven Spielberg, THE GOONIES follows a group of misfit kids (including such second-generation Hollywoodites as Josh Brolin and Sean Astin) as they search for buried treasure in a subterranean cavern. Here they cross the path of lady criminal Mama Fratelli and her outlaw brood. Fortunately, the kids manage to befriend Fratelli’s hideously deformed but soft-hearted son, who comes to their rescue. The Spielberg influence is most pronounced in the film’s prologue and epilogue when the viewer is advised that the film’s real villains are a group of “Evil Land Developers.” Registration is recommended.
