The setting is an area in the Wild West terrorised by a violent outlaw gang who have the corrupt sheriff in their back pocket. Into this enters a mysterious loner who takes it upon himself to protect the people against these criminals by joining the gang and infiltrating them from within.
From the above synopsis it should be clear to any seasoned fans of spaghetti westerns that A Coffin for the Sheriff (great title, pretty irrelevant though) is a film with some very familiar plot elements seen in many other entries in the sub-genre. But in fairness, this is a pretty early entry in the Italian western cycle of movies and so these clichés weren't quite as cemented in as they were going to be by the end of the 60's. This one was helmed by Mario Caiano who, like most of his Italian contemporaries, made a number of films in the different popular genres of the given year; the best of the one's I have seen is his impressive Agatha Christie styled giallo Eye in the Labyrinth (1972). With this one, it's really more a case of business as usual, as opposed to an entry that brings anything new to the table. It is one of the sub-sets of spaghetti westerns that fall under the revenge-themed bracket and I thought it essentially delivered its goods in an effective and entertaining enough manner. The star of the show is Anthony Steffen, who seemed to specialise in roles such as this one; he is a fairly limited actor in many ways but fits the persona of spaghetti western anti-hero pretty well it has to be said.
Ultimately, this one is more of the same but more of the same is okay sometimes and it's perfectly acceptable when it's based around an original formula which is so dependable to begin with.
