Carry on Columbus

Christopher Columbus (Jim Dale) believes he can find an alternative route to the far East and persuades King Ferdinand (Leslie Phillips) and Queen Isabella of Spain (June Whitfield) to finance his expedition. But the Sultan of the Ottoman Empire (Rik Mayall), who makes a great deal of money through taxing the merchants who have to pass through his country on the Silk Road, sends his best spy, Fatima (Sara Crowe), to wreck the trip.
