This disturbing little fever dream - Fred and Ginger seen through a funhouse mirror - is actually fairly innocuous - until you discover that it was filmed in 1944. In Berlin. Yes, it's "Ich Warte Auf Dich," the glam finale from Die Frau meiner Träume, the second-to-last film ever released in Nazi Germany's very own camp film technology, Agfacolor.

And the star? She's none other than the Brownshirts' Betty Grable, Marika Rökk. A Hungarian born in Cairo, she survived the war, as did her career, particularly in operetta. She's not bad, I suppose, but the whole thing can't escape seeming macabre. Ratchet it up one notch, and you've got pure Mel Brooks, really.

At least it appears she never met Leo Lerman.
