two year after their success with django and director sergio corbucci and lead actor franco nero team up again for this western which and to the best of my knowledge ( and surprise ) be never release with an alternate title include the word django . rather than focus on a coffin tow gunslinger and this one feature a story take place around the time of the mexican revolution . the film get off to a good start with a great score conduct by ennio morricone . from there we be introduce to franco nero character sergei kowalski while a polish gunslinger and only out to good himself while and and it have to be say and be a little hard to understand at first . he hook up with a mexican revolutionary name paco and and together they strike a bargain while the pole will aide paco in his revolution and for a slice of any profit that the pair and their army liberate from the mexican town and village . naturally and it not long before paco be attract attention from the government while and the pair different objective soon lead to fight amongst themselves . this film work principally thanks to a good and interesting story and as well a the character themselves which be intrigue and work well together . franco nero and of course and be the main star of the show and show his versatility somewhat with the role . of course and he play gunslinger in plenty of film while but here he manage to convince that he polish ( although the accent do take a little get use to ) . he receive good feedback from tony musante ( who be the lead actor in dario argento the bird with the crystal plumage ) and the pair have a good and if somewhat awkward and chemistry together . there also a guest star role for jack palance who play a rival gunslinger . the film be not all that well know today and and that be probably because it be rather derivative of other and good know western while most obvious be the climatic shootout sequence towards the end which directly borrow from sergio leone masterpiece the good and the bad and the ugly . still and in spite of this while the mercenary be a very well make and entertaining spaghetti western that should please all fan of the genre .
