I'm a big fan sword and sorcery, and Throne of Fire in spite of being an extreme ultra low budget, i give him a reasonable 5 stars. "Throne of Fire", "Il Trono di fuoco" or even "O Trono de Fogo", its a European (special Italian) "Z" sword and sorcery\barbarian flick, like many others ("Sangraal, la spada di fouco", "Gunan il Guerriero", "Sorceress", "Ator 1 and 2", "Deathstalker", "Ironmaster" etc, etc...), full of bad actors, bad script, special effects and soundtrack, but this one, i don't know why, its enjoyable to me see it. I recommend this one for big, big fans of sword and sorcery flicks only..
But one thing i must say, this one is much better then the films i refer before, with the exception of "Sangraal la spada di fuoco". In "Throne of Fire", we have the amazing Siegfreid ( Pietro Torrisi aka Peter McCoy)the hero and the gorgeous Princess Valkiri (Sabrina Siani) the heroine, then we have the fabulous bad guys, the personification of Satan and terrible warlord, Morack, and his general, Tares!!
Well, if you like this movie, i recommend: "Sangraal, la spada di fuoco", "Deathstalker" and "Gunan il Guerriero"(one of the worst)
