Half-a-century in, the sultry Kim Cattrall continues to keep it real. Real hot, that is, thanks to her frequently naked turn as the nymphomaniacal Samantha on HBO's Sex in the City. Still, for all that series' metropolitan sass and class, Kim's howlingly hilarious breakthrough as the loudly orgasming Lassie in Porky's (1982) remains a fan favorite and a masterpiece of muffshish. Alas, Kim sought to end her stint on Sex in muff the same fashion that we first got to know her--going fantastically full frontal on the show's final episode. After Sex's run ended, she turned her attention to penning books--Satisfaction: The Art of the Female Orgasm and Sexual Intelligence--about being a fully mature--and totally horny--older woman. For Kim, fifty sure looks nifty.
