Before Sunset stars Julie Delpy and Ethan Hawke's dreams of teaming up again for a vampire spectacular have been dashed - because the actor is too busy on stage. An American Werewolf In Paris star Delpy wanted her pal to play a cameo in her new vampire film, The Countess, but his schedule doesn't allow it. Speaking to internet gossip Marc Malkin, she says, "He's been out of the picture for a while... He's doing a play right now, and I'm not going to stop my film for two days of work. "It's not a big deal; he was doing it for fun, for me." The couple is currently looking for another starring project to do together.
