Chicago Sun-Times by Roger Ebert

Ritt directs with a steady hand, and the dialog by Irving Ravetch and Harriet Flank bears listening to. It's intelligent, and has a certain grace as well.

Hombre develops the theme that socially and morally disparate types are often thrown into uneasy, explosive alliance due to emergencies. Paul Newman is excellent as the scorned (but only supposed) Apache. Fredric March, essaying an Indian agent who has embezzled food appropriations for his charges, also scores in a strong, unsympathetic – but eventually pathetic – role. Richard Boone is very powerful, yet admirably restrained as the heavy.

One of Ritt's best films, with fine performances all round, impressive Death Valley locations, and superlative camerawork from James Wong Howe.

The New York Times by Bosley Crowther

Hombre seems constantly meaning to have something vital to say, maybe about racial antagonisms, that it can't quite sputter out because it has so much to do. But in the doing of it, all the people are fine in their roles and the whole is tremendously engrossing without being important. Hombre is tough.

It's an extremely violent and brutal film, featuring a fine performance by Newman. He's a blunt, practical man who favors action over words. Cilento is appealing as the worldly landlady, and Boone is chilling as the sadistic bad man who is ready to murder anyone standing in his way.
