This Warren Beaty movie from 1966 may be of interest to some of you with region-free DVD players:
A cardsharp comes up with the ultimate system for beating the casinos at their own game in this high-style caper comedy. Barney Lincoln (Warren Beatty) is a footloose playboy with a taste for gambling and an ingenious scheme for winning at the leading casinos in Europe. Barney discovers that nearly all of the major gambling houses use playing cards manufactured by the same company; by breaking into their plant and subtly altering the printing plates, he's able to mark the cards with a code only he can read, and he is soon pulling in record winnings across the continent.
