Saw this a long time ago, but as I recall it was a pretty ordinary war movie. The only thing that distingishes it is the presense of Harrison.
Leonard Maltin/Plot synopsis:
Awful sequel to classic GUNS OF NAVARONE, poor in all departments, although Shaw, Ford, and Nero try to give it a lift. Mixed group (naturally), hindered by traitor Nero, attempt to blow a bridge vital to Nazis. They blew the film instead. Based on the Alistair MacLean novel. Restored to 128m. on laserdisc. Panavision.
