A Genius, two Partners and a Dupe – Nobody is the Greatest (Damiano Damiani, 1975) is the first movie I’ve seen in my life.
So I must mention Terence Hill‘s website; there is a wide archive of photos and informations about his movies.
And, most of all, his famous recipe: the bean dish seen in the spaghetti-western They Call Me Trinity (E.B.Clucher, 1970).
