A note to Cate Blanchett and Reese Witherspoon: Woody Allen has his eye on you. “These are two actresses that I would like to work with, because I think they're both very talented,” Allen said at the Cannes Film Festival, where his latest tale “You Will Meet a Tall Dark Stranger” premiered Saturday. “But I don't know them. I've never had the opportunity to speak with them.” Allen tossed out the two names to reporters when asked what actors he would like to cast. He missed Blanchett by only a couple of days: she was at Cannes Thursday for “Robin Hood,” in which she stars with Russell Crowe. Allen's new film stars Naomi Watts, Anthony Hopkins, Antonio Banderas, Josh Brolin, Gemma Jones and Freida Pinto.
