It's got some of the best shipboard battle scenes I've ever seen, along with some great lines, wonderful interaction between the characters, and a brilliant twist ending!
My healer character Aerden, though, thinks Dr. Maturin is a far braver man than he is. (g)
The movie stars Russell Crowe and Paul Bettany, who starred together in A Beautiful Mind, as well.
If you should see the movie and happen to like the characters of Captain Jack Aubry and Dr. Stephen Maturin, you can read the whole series of books about them by Patrick O'Brian.
