Appointment with Venus

Don't be misled by the title, and by the presence of Glynis Johns in the cast. The 'Venus' in Appointment with Venus is a prized cow. The time is World War II: special operatives David Niven and Glynis Johns are dispatched to a Nazi-held island to rescue Venus, who for some reason or other is vital for British morale. Not only Venus but a whole herd of bovines have to be smuggled out right under the German's noses (they all must have head colds). (official distributor synopsis)
