Ruthless (1948) is a classic film noir directed by Edgar G. Ulmer, starring Zachary Scott, Louis Hayward, and Diana Lynn. This forgotten noir gem explores the dark side of ambition, power, and betrayal through the rise and fall of a ruthless financier, Horace Vendig.

This vintage noir drama captures the signature style of late-1940s Hollywood: chiaroscuro lighting, complex flashbacks, and a moral tale of corruption and revenge. Ulmer’s direction and the performances deliver a biting commentary on postwar greed and the emptiness of success — hallmarks of the film noir tradition.

If you’re a fan of classic noir, psychological thrillers, or Edgar G. Ulmer’s moody storytelling (like Detour), this is an essential watch.
