Anybody remember an old movie name of Our Man in Havana ?

There was a checkers game between the vacuum cleaner salesman about to be deported as a spy (Alec Guinness) and the Jefe de Havana Police (Ernie Kovacs) with the pieces being miniatures of light or dark rum. When you jumped a piece you had to drink it.

The relative skills of the players very quickly ceased to be of significance...

It's one of a small number of movies better than their progenitor books.
