Operation Crossbow (1965) - The Outcome Of The War

Opening, the point being that this is a full-scale Carlo Ponti WWII espionage feature, starring his wife Sophia Loren, and lots of people got their names billed before the title; also Churchill (Patrick Wymark) himself is involved, visited by Richard Johnson as Duncan Sandys (a historical figure, actually Churchill’s son-in-law), from Operation Crossbow, 1965.
