Equation to an Unknown

Dir. Dietrich de Velsa


A handsome young stud rides his motorcycle through a myriad of sexual fantasies, from a soccer game's locker room to a dreamy and unsettling orgy where the porn reaches its melancholic peak. This undiscovered erotic film is a labyrinth of all-male fantasies whose outstanding beauties always end up fading away while leaving their sensual protagonist dealing with his own loneliness. Directed with absolute grace by the mysterious Dietrich de Velsa (aka Francis Savel / Frantz Salieri): this former painter was also the owner and artistic director of one of the first transvestites' cabaret of Paris, La Grande Eugène. Years later, he collaborated with Joseph Losey on Mr. Klein and Don Giovanni. EQUATION TO AN UNKNOWN is his only film and stands without a doubt as a masterpiece and the best French gay porn ever made.

Year of production: 1980. Running Time: 99 min
