Lee Marvin's favorite movie
according to his wife, Pam in her biography, Lee.
"Just after Lee and I were married he had the movie run for me. It was the only time he did this; and he told me privately that it was his favorite. He did not like publicly to admit to having a favorite, and when asked in interviews, his standard answer was, 'the next one.')
By the way, he lost 40 pounds in the nearly five months it took to rehearse and shoot the movie.
