Poor Millionaire (1965)

Let's face it, Petros, a self-assured and successful international entrepreneur, does not believe in love. Handsome, young, and wealthy, Petros has had multiple affairs with various women in the past; however, none of them managed to talk him into tying the knot. But, now that Lisa, a charming medical student and auto show model, has caught his eye, things are bound to take an unexpected turn. Before long, Petros decides to play a trick on Lisa to test her honesty, and as a result, he ditches his elegant suits, and slips into something more comfortable, posing as a jobless and stone-broke suitor. Will the penniless millionaire manage to win Lisa's heart?
