In the Film Programme this week Francine Stock talks to the director of Atonement, Joe Wright about his new film, Hanna; the charismatic Christoph Waltz, who stars in Water for Elephants, discusses the craft of screen acting; and the film historian Neil Brand reflects on cinema's ironic use of music. There's also a look back to two cult films released in 1968 - Bob Rafelson's Head and the even rarer Joanna, directed by Mike Sarne, which has just been released on DVD.
