The two leads Newman & Marvin are based 100% upon the actual lives of the two brothers J.P.S. Brown & Gene Adams, two authentic cattle buyers in Mexico and horse traders. Gene Adams a half brother of Joe Brown, the two toughest cowboys in Arizona history. The novel written by J.P.S. Brown Jim Cane is authentic reality. Gene has passed away but Joe Brown lives in Sonoita ,AZ Google my friend J.P.S. Brown all his novels are the best Western genre one can read. Marvin dressed in suit because he did not need to wear Western costumes, he & Joe were in Mexico on business.
