Double Bunk is a British black-and-white comedy film set on a houseboat. It was released in 1961, and stars Ian Carmichael and Sid James. Plot Facing eviction from their London flat, newlyweds Jack (Ian Carmichael) and Peggy (Janette Scott) are tricked into buying a rundown houseboat by its current owner Alfred Harper (Reginald Beckwith) and his put-upon wife (Irene Handl). Mr Watson (Dennis Price), who owns Jack and Peggy’s mooring, soon makes their acquaintance by introducing them to his mooring tariffs and associated surcharges. Jack's used-car-salesman friend Sid (Sid James) helps him rebuild the engine, and the newlyweds take the boat down the River Thames to Ramsgate with Sid and his girlfriend Sandra (Liz Fraser) as passengers. On the way they have trouble with an official from the Thames Conservancy (Naunton Wayne) and a member of the river police (Terry Scott). After Sandra's transistor radio gets misplaced next to the compass, they end up in Calais. With no fuel or supplies they must resort to desperate actions to get themselves and the houseboat back home. Sandra puts on a striptease for Watson, who also happens to be in Calais, so Jack and Sid can "borrow" some of Watson’s fuel and food. The next morning they follow Watson back across the Channel, as their own compass is broken, and enter into a wager with Watson on who can get back to their mooring first. They win the bet when Watson's boat runs aground. Background The houseboat, "Jasmine Cot", was actually "Joan Mary", an Admiralty 48-foot "Personnel Launch, Diesel" conversion. She was based at Newmans Shipyard, 1, Strawberry Vale, Twickenham. Soundtrack The musical score was composed by Stanley Black, and the title song, sung by Sid James and Liz Fraser, was by Stanley Black, Jack Fishman and Michael Pratt (later better known as the actor Mike Pratt).
