Equation to an Unknown (★★★☆☆), originally released in 1980, winds a wild path through a young hero’s love life.Long lost to the vestiges of memory, the film, directed by Francis Savel under his nom-de-porn Dietrich de Velsa, was rediscovered by French filmmaker Yann Gonzalez (Knife + Heart), who commissioned a new print from the original camera negative, resulting in this gorgeous video transfer, now available for streaming on Pinklabel.tv.Dark-haired looker Gianfranco Longhi stars as a brooding, enigmatic motorcyclist who speeds around his French industrial town seeking, or just stumbling upon, scenes of sexual pleasure.
