Force 10 from Navarone
Force 10 From Navarone was a sequel to the 1961 blockbuster The Guns of Navarone and tells the tale of ten widely divergent WW II troubleshooters who attempt to blow up a crucial bridge in Yugoslavia. As in the first Navarone film, one of the guerillas is a traitor: group leader Mallory (Robert Shaw) knows the identity of the turncoat, but can't prove it until it's almost too late. The beautiful female resistance leader is played by Barbara Bach, while Harrison Ford, fresh from his Star Wars success, is the romantic lead. Others in the cast include Edward Fox, Franco Nero and Alan Badel.
