although ww2 movies can be entertaining, with a hand-picked group of actors who can do comedy bits, this movie is one of the best pulse-pounding suspense movies in a ww2 setting. there is no time or place for cute march like tunes, or jokes. Burt Lancaster gives a towering performance as the engineer. Paul Scofield as the nazi colonel has fewer lines, but is riveting in his face and eye expressions. I saw this movie some years ago, and it made the same impressions.
