What Changed Charley Farthing stars Doug McClure as a wayfaring sailor stopping over in Havana. In the tradition of The African Queen, the sailor becomes a reluctant hero when he is hired to give safe passage out of Cuba to a young woman (Hayley Mills) and her father (Lionel Jeffries). This involves stealing a boat, ducking the authorities, and avoiding bullets. David Pursall and Jack Seddon adapted the screenplay from a novel by Mark Hebdon. What Changed Charley Farthing has been run repeatedly on American television under its alternate title The Bananas Boat.
