Force 10 From Navarone (1978, U.K.)

Returning from their successful mission, the destruction of the guns of Navarone, Mallory (ROBERT SHAW) and Miller (EDWARD FOX) are sent to Yugoslavia on another almost impossible assignment  During their journey, they join up with Force 10, a group of tough American commandos led by the daring Lt. Colonel Barnsby (HARRISON FORD).  But, on arrival in Yugoslavia, they are captured by the Germans, and failure of the mission seems certain.
