Appointment with Venus on AllMovie

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. Naturally, this isn't easy and leads to all sorts of complications. Released in the US as Island Rescue, Appointment with Venus was based on a novel by Jerrard Tickell.
