"Nove Ospiti per un Delitto" is a mediocre giallo in the tradition of Agatha Christie's "And Then They Were None". Nine members of the same family go to an island, where nobody lives - but the head of the family (Arthur Kennedy) owns a nice house there. Problem is that he and his three sons keep a dark secret, and this dark secret begins to haunt them as soon as they are on the island. One by one falls victim to a mysterious killer.
Arthur Kennedy leads a remarkable male cast in this rather low-budget-effort which fails to thrill the audience. John Richardson gives too a fine performance, just as do Massimo Foschi (protagonist in Ruggero Deodato's impressive "Ultimo Mondo Cannibale") and Venantino Venantini. Unfortunately, as mentioned before, the movie itself is nothing special. Director Baldi fails to deliver a thrilling atmosphere, even though he tries to do so. The most interesting thing is that none of the characters are sympathetic; they are all rather mean and selfish, so nobody really cares when somebody dies... Only interesting for fans of the giallo genre or fans of the surprisingly good male cast.
