Zarah Leander, the Swedish singer, became "the diva of Nazi Germany" in the late thirties; with her dark, deep voice, sultry manner and (with proper lighting) luminescent visage, she was something of a cross between Dietrich and Garbo, and a natural heir to the Dietrich throne (abdicated in 1930). Ufa went all the way with Leander, casting her in films by Douglas Sirk (Zu neuen Ufern, La Habañera), Carl Frölich and other top name directors, and it paid off; she was one of Hitler's favorite actresses, but she turned down Goebbels' offer of citizenship to retire to Stockholm in 1943. Documentary filmmaker Christian Blackwood (Tapdancin', By Myself, etc.), who was born in Berlin in 1942 and emigrated to the U.S. as a child, discovered the legendary Leander a little late-after her death in 1981-but, undaunted, he determined to make a film portrait of the star. The project took shape when he met Paul Seiler, a fan who literally devoted his life to Leander, pestering his way into her world and becoming the singer's confidant, dresser, substitute son or lover...and, after her death, curator of a vast store of memories and memorabilia. Seiler's true confessions are central to this film about what it is to be a fan, what it was to be a superstar during the Third Reich, and how low and how long a star, once risen, can fall. A television interview with Leander, made shortly before she died, and film clips are skillfully intertwined with interviews with Sirk and other directors and actors who worked with "The Divine Zarah."
