Some friends of mine and I talked with Peter Graves a little over a year ago and he said that Dario Argento had nothing to do with the making of FIVE MAN ARMY. He said that the whole movie was directed by the American, Don Taylor, regardless of what rumors have been perpetuated throughout the years.
Also, Brett Halsey (Montgomery Ford) told us the same thing in regards to TODAY IT'S ME..TOMORROW IT'S YOU. He said that Argento might have had a small role in the writing of the screenplay; but, that was all.
And Sergio Donati says that Argento didn't really work on any of the drafts of ONCE UPON A TIME IN THE WEST. Donati says that Argento was merely at one of the story conferences for Leone's film and contributed a small amount to the film in that way.
But, I cannot argue at all that Argento made some classic Giallos!!
I voted for (in random order): Leone, Corbucci, Sollima, Petroni, Castellari (Girolami), Guerrieri (truly an underrated director, in my opinion!), both Marchents, Baldi, Baldanello, Tessari (for his Ringo films, if nothing else!), Giraldi, Valerii, Parolini (on the strength of the very first, and in my opinion the best, Sartana film!), and Cardone.
No need to update the poll, amigos; but, I just happened to think of another director I like very much that is often overlooked and underrated.
That is Aldo Flori, the man that gave us ANDA MUCHACHO SPARA! (w/Fabio Testi) and FIVE GIANTS FROM TEXAS (w/Guy Madison)...two of my favorites! I just wanted to mention him.
