Marni Nixon, secret singing voice of Wood, Hepburn, et al. dead at 86

She was the voice (often uncredited) doing the singing for Natalie Wood in West Side Story, Audrey Hepburn in My Fair Lady, and Deborah Kerr in The King and I, among others.

RIP. It must have been odd to have been the voice for so many classic musicals but have most of the world never realize it!
