You Must Be Joking! is a 1965 black and white British comedy film directed by Michael Winner and starring Michael Callan, Lionel Jeffries, and Denholm Elliott. The format of the film, four people each doing six tasks linked to a scavenger hunt, allows for 24 otherwise somewhat unconnected comedy vignettes, which jointly create the story line. The items (purportedly representing British identity) include flying ducks for the wall, an English rose, the Spirit of Ecstasy from a Rolls-Royce car, an electric hare from a greyhound race and the Lutine Bell. Plot Major Foskett, a British Army psychologist, assembles four soldiers for a testing task: Sergeant Major McGregor (complete with kilt and bearskin), Captain Tabasco, Sergeant Clegg (a father of nine), Staff Sergeant Mansfield and United States Air Force Lieutenant Morton. They have their initiative tested in a scavenger hunt. Their first task is to escape a maze. Tabasco orders up a helicopter to take him out and two others take a ride, but Clegg is left in the maze. They are instructed to obtain six items, supposedly symbols of the British way of life. The reward for the winner is to be fast-tracked for promotion and a ten-day, all-expenses-paid trip around the world for two. Among the feats to be accomplished within 48 hours are escaping from a maze, retrieving a rare rose and the mascot from a Rolls-Royce motorcar, and procurement of a lock of hair and an autograph from a popular French singer. The final challenge involves the famous Lutine bell from the Underwriting Room of Lloyd's of London. MacGregor arrives at the finish line by parachute, Tabasco comes in an ambulance, Clegg digs his way in from below. Morton arrives last (by car), but is declared the winner and resigns. General Lockwood is arrested for misuse of the requisition system. Foskett is arrested for conspiracy to steal the Lutine Bell.
