giuseppe colizzi was a fine underrated director dead too early that invented the characters of Spencer-Hill. Differently from E.B.Clucher, Hill is more Eastwood-way then Trinità but the substance is the same. Colizzi was a well competent director, more american then italian, with strong sense of spectacule and correct with the particulars. In Italy is very underrated, I don't know why. "Ace high" is, probably, his best western. It's also hard to see his movies in tv. You can only see every summertime "Arrivano Joe e Margherito", but this is not his best. I hope one day critics rediscover the art of this modest, hard worker artigian of the screen.
