Nicole Kidman thinks her new movie `Rabbit Hole` has a "hopeful" message. The `Australia` actress and co-star Aaron Eckhart portray a couple who struggle to cope with the death of their son in a road accident in the big-screen adaptation of stage play `Rabbit Hole` as but Nicole is adamant the film is not completely heartbreaking. She told US TV talk show host Conan O`Brien: "I actually think it`s very hopeful. It shows what happens when people go through an enormous loss and it shows that you can stay together. It`s about a family and how it copes with this. "It deals with many other things too. I say it`s a small film but it actually does deal with a lot of issues." Nicole revealed she decided to become a producer on the film because she was so passionate about getting it made. She said: "I produced it which was a great thing to do because it so hard to get it made because it`s such difficult subject matter. It`s such a beautiful film, it`s real." The film - directed by `Hedwig and the Angry Inch` filmmaker John Cameron Mitchell - deals with how the couple cope after the driver of the car that killed their child contacts them seeking closure from the incident.
