Three on a Spree is a 1961 British comedy film directed by Sidney J. Furie, based on the 1902 novel Brewster's Millions, which had been previously filmed by Edward Small in 1945.
Michael Brewster stands to inherit £8000,000; but only on condition he spends the first million in sixty days.
The New York Times found it "all unbelievable and more than a little unpleasant."
