Being a Spanish rather than Italian production, I don't think this rates as an official Spaghetti Western yet, it's been included with a clutch of such efforts in a budget-release Box Set (which I've rented and am currently going through); the treatment itself, in fact, isn't even really evocative of that distinctly baroque style!
The film-makers managed to acquire two American stars for this one: veteran Joseph Cotten and William Shatner (a fashionable commodity at the time thanks to the STAR TREK phenomenon on TV); they actually complement each other quite well, the reliable Cotten being a laid-back yet plain-speaking marshal and Shatner brooding albeit given occasionally to his trademark histrionics especially since he plays twins, i.e. cowboy hero and the troublesome half-breed of the title!
The narrative also incorporates a subplot involving rival factions fighting for control of the town of Rio Hondo; female interest is provided by lovely blonde Rosanna Yanni (co-star of the two "Red Lips" films by Jess Franco made the previous year), who's assaulted by one Shatner and loved by the other. Eventually, the two siblings face-off in a duel on horseback which both undertake bare-chested and wearing a bandana (presumably, to confuse the audience as to the identity of the victor)! At the end of the day, the film proves a tolerable diversion if nothing more unless one counts Shatner's almost campy intensity (particularly in his caricatured Indian portrayal) as an added source of gratification! I should also mention here that the terribly inappropriate jazzy score is a pain to listen to and, besides, the pan-and-scan version I watched had an irritating tendency to jump-cutting within the same shot in search of the current speaker's face!!
