Released in the US as Man With a Million, The Million Pound Note is a satisfying adaptation of a satirical short story by Mark Twain. Gregory Peck plays Henry Adams, an impecunious American living by his wits in London. Henry becomes the object of a wager between millionaire brothers Oliver and Roderick Montpelier (Ronald Squire and Wilfred Hyde-White), who want to find out if a man with a million pound note in his bank account could live comfortably for one month on the strength of that note--without ever spending a penny of it. When Henry is given the note and lets it be known that he has it, every courtesy imaginable is extended to him by hoteliers, restauranteurs, etc. Trouble brews when Henry uses the note's reputation to speculate on the stock market. When his creditors demand that he produce the note as an act of faith, Henry is unable to do so, whereupon pandemonium reigns--and the audience's laughter cascades.
