Sons Of Katie Elder, The

Led by big brother John Wayne, the four sons of ranch owner Katie Elder set out to avenge the murder of their father and the swindling of their dear old Ma. Dean Martin shows his acting chops and George Kennedy is on typically villainous form but look out for a young Dennis Hopper in a rousing revenge drama that was (dodgily) updated for the 21st century as Four Brothers. Trivia: John Wayne had to breathe using an oxygen tank because the film was shot so high in California's Sierra Nevada.
