Dubbed by Andrew Sarris ""the Citizen Kane of pop musicals,"" recently given a high-profile release on a two-disc DVD, "A Hard Day's Night," directed by Richard Lester, is viewed by Stephen Glynn as that rare event--a cheap exploitation movie that has entered the cultural canon. Following the Fab Four's adventures in New York the film established enduring individual personalities for the four Beatles, invented the pop music video and made us all ""buy into"" the Beatles. This radical "Guide," full of detail and insight, explores its making, its music, fandom, Pop Art style, reception and influence and how the Beatles went to America to make a revolutionary movie.
