While in a philanthropic meeting promoted by the millionaire Horace Woodruff Vendig (Zachary Scott), the guest Vic Lambdin (Louis Hayward) tells the history of the beginning and end of his friendship with the host to his date Mallory Flagg (Diana Lynn). When they are boys, Horace is a poor boy from a dysfunctional family and Vic's best friend that saves the wealthy girl Martha Burnside from drowning in a river. Horace is adopted by the rich Burnside family and later sent to Havard and gets engaged to Martha, for whom Vic has a crush. When the ambitious Horace meets the wealthier Susan Duane (Martha Vickers) that belongs to a more influent family, he calls off his engagement with Martha and moves to New York with Susan continuing his social raise. Later he meets the shark Buck Mansfield (Sydney Greenstreet) and seduces his young wife Christa (Lucille Bremer) to profit in business, leading to tragic consequences.

I was zapping the cable TV this raining Sunday morning in Rio and I found this rare film-noir by chance, which has never been released on VHS or DVD in Brazil. Edgar G. Ulmer made a magnificent movie with a timeless plot of merciless ambition of a poor and selfish boy that wishes to climb financially and socially using and disposing wealthy women and friendships. The screenplay uses flashback to perfectly develop the lead character and his acquaintances, supported by awesome black and white cinematography and camera work. My vote is eight.

Title (Brazil): "O Insaciável" ("The Insatiable")
