This feline femme fatale has been extant since the very earliest days of Batman’s crime fighting career, and it’s pretty easy to see why she’s been worth keeping around. With her skintight catsuit and seductive purr, Michelle Pfeiffer’s puissant pussycat makes even the Dark Knight a-throbbing. Not bad for a 70-year-old. Originally named Selina Kyle – a bedraggled and introvert secretary – Pfeiffer’s character is transformed into Catwoman after being thrown out of a lofty office window in 1992′s Batman Returns. She is then somehow revived by a host of feral cats and goes home to sew a costume together before exacting sexy revenge. Meow! It remains to be seen if Anne Hathaway’s upcoming portrayal of Selina Kyle in The Dark Knight Rises can challenge Pfeiffer’s sensual endeavor.
