John Wayne plays a lawman who has to deal with the problems of fatherhood in a big way in Cahill: United States Marshall. Wayne is J.D. Cahill, whose singular desire to track down law breakers strains his relationship with his two teenage sons --17-year-old Danny (Gary Grimes) and 12-year-old Billy Joe (Clay O'Brien). The film begins as Cahill is hot on the trail of a gang of outlaws. After the big showdown, he returns to town to discover that the local bank has been robbed. The sheriff and the deputy have been killed, and four bank robbers are imprisoned in the jail. He is stunned when he finds out that one of the robbers in jail is Cahill's son Danny. It seems that during Cahill's absence from home, his two sons have been enticed into a criminal life by nefarious outlaw Abe Fraser (George Kennedy). ~ Paul Brenner, Rovi
Filled with a great cast and one of the more original plot premises for a Hollywood Western of it's time, "Cahill" succeeds in delivering entertaining action. Acting, direction and set design are on par with television productions of the period, but the cinematography and "prodigal son(s)" plot-line rise above the average fare. at 103 minutes duration its a bit long for the material, but Westerns are seldom fast-paced beyond the opening "hook" and the climactic showdown. Overall, well worth watching and suitable for families with children in the PG range.
