Query: Once you have read the book, see the movie....

Definitely a good movie. However, I think that if you go into it blind (without having read the book), it will be a little confusing for the first 20 minutes or so. However, once the characters and plot are introduced, the movie can stand on it's own.Michael Caine is very believable as a German officer. Donald Sutherland is a natural for an Irish Rogue.The only reason I give it four stars instead of five is bacause of the first 15 - 20 minutes.
