Purple Noon (1961)

A French telling of Highsmith's The Talented Mr. Ripley, in which the lower class Tom Ripley is tasked by Philippe's father to find him and bring him home. Instead, Tom decides to tag along with Philippe for as long as possible, enjoying the high life he so craves. Eventually, of course, his welcome wears out and he has to get creative to keep the fun going.

Without a clear rooting interest, even a decent thriller like this just can't really have much of a lasting effect. Tom is the villain, but the idle rich he's duping could never be called innocents or heroes, so who really cares?
