Nas Margens do Rio Grande

Mitchum is an assassin in the employ of Mexican mafia/government, and London is the wife of an American major. He becomes involved in Mexican civil disputes and decides to extricate himself too late.

The script brings the characters to life and reveals themes of self-loathing battling the ego in an extraordinary but low-key manner. The character performances are all convincing with the exception of a slight case of oversincerity on London's part. Gorgeous location filming in the deserts and in a Mexican town shot from a hilltop. The action scenes are pretty routine, but they and pretty much everything else is handled in a fairly realistic style, which adds greatly to the film's appeal.
