The film talks about a semi-retired sheriff (Robert Mitchum) who finds his nemesis , an old outlaw (George Kennedy) . He is abandoned by his band (leaders are David Carradine and John Davis Chandler) of cutthroats for being too old to execute a bank-heist that the gang is planning . Demystified Western was one of a group of much-imitated which changed the concept of their particular genre each bent on disproving a popular myth , yet tinged with humor , spoof and combining anti-heroes , replacing cars and horses ; in addition , the inevitable decadence of protagonists . The formula deals to enhance the comic observations of the western originated on the decade of the 60s by the following filmmakers : Andrew McLagen and Burt Kennedy , fine director of this movie .
Burt Kennedy directed similar Western with comedy such as :¨Support your local gunfighter¨ (one of the best spoof Western) , ¨Support your local sheriff¨ (his highpoint) , ¨Dirty Dingus Mcgee¨ and ¨War Wagon¨ . The picture is wonderfully amused and enjoyable with Robert Mitchum as a tough but dreary sheriff with his Maverick image who uses brains as well as brawny and guns . He cleaned a lawless town in his own highly individual way but he is fired by the Mayor , rightly played by Martin Balsam . Mitchum in one of the best interpretations was much stronger actor when being something older than a straightforward hero . George Kennedy makes a robustly likable characterization . Stars have a splendid fight aboard a train towards the end ; furthermore , it contains excellent action sequences , as well as the pursuits and derailing train . Ronald Cohen's screenplay besides having more than its fair scraps of funny lines , throws up rich characters . Thus , Douglas Fowley as the old brawler likeness Walter Brennan (Support you local..) clearly relishing his comic relief . John Davis Chandler , as always, plays a sadist gunfighter. There appears uncredited Christopher Mitchum , Robert's son , along with Buddy Hackett . Film exteriors were shot in New Mexico by cameraman Harry Stradling who reflects stunningly the marvelous landscapes . Jolly and agreeable musical score by William Lava and songs by Ned Washington. The motion picture was well directed by Burt Kennedy .
