Sean Lennon has signed up to score a new low-budget vampire comedy film starring Dustin Hoffman's son JAKE, Devon Aoki and KARATE KID RALPH MACCHIO. In the movie, called ROSENCRANTZ + GUILDENSTERN ARE UNDEAD, Hoffman will play a struggling actor who lands a big break directing an off-Broadway stage version of Shakespeare's Hamlet. Unfortunately, the new adaptation has been written by a Romanian vampire, played by John Ventimiglia. MACchio plays a New York mob boss.
