This nostalgic British import coasts fairly far on charm. It spins the early-'80s-set tall tale of two small-town schoolboys--one a naive lad raised by a fundamentalist mother, the other a rambunctious latchkey kid--who are united by their mad obsession with a pirated VHS copy of Rambo: First Blood. So enamored are these boys with the art of filmmaking, that they attempt to shoot thier own no-budget, two-man sequel. The character drama is undercooked, but the movie-loving in-jokes are a lark. 96 minutes PG-13.
