Nicole Kidman stars as Grace Kelly:
Tim Roth plays Prince Rainier III. Roth has been a favorite of mine since Pulp Fiction and Reservoir Dogs. He was nominated for an Oscar in 1996 for his supporting role in Rob Roy. That award went to Kevin Spacey for his work in The Usual Suspects. Can't really be upset about losing that one.
Frank Langella plays Father Francis Tucker. If you haven't seen Robot and Frank starring Langella, what are you waiting for???
