47 Belgrave Square, SW1

Ronald Neame’s 1954 comedy The Million Pound Note stars Gregory Peck as Henry Adams, a penurious American given the titular note by fabulously wealthy brothers Roderick and Oliver Montpelier (Wilfrid Hyde-White and Ronald Squire). The joke (although he’s loaded with cash, no one can change the note) came from a Mark Twain story, and was pretty much recycled by John Landis in 1983 as Trading Places.

47 Belgrave Square is the home of the Montpelier brothers. The centre of Belgravia, to which it gave its name, and home to many embassies, this posh London square is no stranger to movies. 17 Belgrave Square (now the Royal College of Psychiatrists) was the home of globetrotting Phileas Fogg (David Niven) in Mike Todd's 1956 cameo-studded epic Around the World in Eighty Days. In Stanley Donen’s glossy 1958 romance Indiscreet, Ingrid Bergman was wooed by Cary Grant at 13 Belgrave Square (now the Ghana High Commission).
