"Variety" magazine likewise praised the acting and discussed the film's major theme, writing, "The theme of "The Defiant Ones" is that what keeps men apart is their lack of knowledge of one another. With that knowledge comes respect, and with respect comradeship and even love. This thesis is exercised in terms of a colored and a white man, both convicts chained together as they make their break for freedom from a Southern prison gang. The performances by Tony Curtis and Sidney Poitier are virtually flawless. Poitier captures all of the moody violence of the convict, serving time because he assaulted a white man who had insulted him. It is a cunning, totally intelligent portrayal that rings powerfully true...Curtis delivers a true surprise performance. He starts off as a sneering, brutal character, willing to fight it out to-the-death with his equally stubborn companion. When, in the end, he sacrifices a dash for freedom to save Poitier, by saving him from the swamp, he has managed the transition with such skill that sympathy is completely with him."
