Laurence Harvey walks up St James's Street to the Economist Buildings:
In the foyer his character (Joe Lampton) meets an old friend and they cross the Plaza together:
Life at the Top is the first (to my knowledge) of several films in the decade to make use of this remarkable set of buildings, completed in 1964. In the next three years it appears in Blowup:
