Clint Eastwood completists will be lining up Monday at Film Forum to see one of his most elusive films, “Le Streghe,” which apparently has never been shown on TV or released on video and has scarcely been heard of since its very limited 1967 U.S. release under the title “The Witches.”

Made two years earlier in Italy — when Eastwood was dividing his time between the final seasons of “Rawhide” and the spaghetti westerns that made him an international superstar — “Le Streghe” was a failed attempt by legendary producer Dino De Laurentiis (most recently responsible for “Hannibal Rising”) to revive the career of his then wife, Silvana Mangano (“Bitter Rice”).

Dino put together an omnibus film consisting of five segments starring Silvana and directed by such notable Italian directors as Luchino Viscounti and Pier Paolo Pasolini. Eastwood plays a college professor married to Mangano in the only English-language section, directed by the formerly renowned Neorearist Vittorio de Sica (a year before de Sica collaborated with Neil Simon, Peter Sellers and Victor Mature on the screamingly funny “After the Fox”).

“The Witches” is showing as part of Film Forum’s tribute to composer Ennio Morricone, along with Sergio Sollima’s even more obscure “Revolver.” Next maybe they can track down a print of “The First Traveling Saleslady” (1956), in which an even younger Eastwood plays the love interest for … Carol Channing.
