It was a movie about some sort of City trader - he supposedly commuted to work from his estate in the Home Counties, where he had a pond with underwater lights for landing at home in the dark.
It'll come to me in a minute - I think Rebecca de Mornay was in it.
Later: It was called "
Dealers" and starred Paul McGann and, yes, Rebecca deM. 1989, and you call it an "old movie". How ancient am I?
