Sigourney Weaver's 'brief encounter' in ALIEN and Kim Basinger's 9 1/2 WEEKS staircase sex scene have topped a new internet poll of unnecessary movie nudity. The actress' saucy scenes join Arnold Schwarzenegger's naked time travelling moment in THE Terminator and hairy Robin Williams letting it all hang out in THE FISHER KING in a new MSN.com list of 10 Revealing Scenes We Didn't Need To See. The not-so-hot list also includes Melanie Griffith vacuuming in her lingerie in WORKING GIRL, Julie Andrews going topless in S.O.B. and Jack Nicholson and Kathy Bates' naked jacuzzi scene in About Schmidt.
