John Cusack has worked with some heavy Hollywood hitters like George Clooney, Adrien Brody, Anjelica Huston and John Malkovich, but who does John think is really a "great actress?" Hilary Duff! The two worked together on the upcoming War, Inc. and John actually requested Hilary for the movie. "I think probably people wouldn't know how talented she is. I mean, she's a great actress," says John. "I just spent the entire fall with her and she was a revelation every day." Uh-oh. Sounds like he's one small step from a Lloyd Dobler moment: Don't be surprised if we catch him standing outside Hilary's window playing "In Your Eyes" later this week!
