Anyone who has memories of the early 1980s, no matter how vague, can recall the plaintive opening vocal rise of the 1983 new wave hit from Germany, "99 Luftballons." Mixed in with the sensory recollection of that saccharine but soul-wrenching guttural cry and subsequent bouncy pop melody is a less vague remembrance of a female singer cavorting and emoting with starry-eyed face lifted beseechingly and mildly scoldingly to the camera in a pose of heartfelt but pretty angst that would become a template for generations of warbling, socially aware songstresses to come. The band and the singer were both named Nena, and the main reason she is remembered and they are forgotten is that video exalts the hot chick star. Another reason is that Nena got nude in the film Gib Gas - Ich will Spass! (AKA Hangin' Out) (1983). Her boobs hang out in this musical comedy, although you'll have to squint to make out the nipples--if they exist at all. Her panty-clad ass also gets lots of attention from the camera. Four years later, Nena steamed up more screens via her performance in Der Unsichtbare (1987), also known as The Invisible Man, but we like the original title better. It's rumored that the pop star gets bare in Der Unsichtbare but Mr. Skin does not have photographic evidence. Aside from those two flicks, Nena has done very little acting save for her countless music video gyrations. She has sold 25 million records and ended 25 million genetic records. We mean sperm.
