Rare is the skinema fan who is alien to the allure of tall drink of hot water Sigourney Weaver. Sigourney did for cotton panties in Alien (1979) what Sharon Stone would do for white scarves in Basic Instinct (1992). She took a lowly staple out of the woman's accessory drawer and elevated it to a fetishistic trigger. Educated at Stanford and Yale, this five-foot-ten-inch thespian is smart enough to know that if movies are supposed to be about real people, they take off their clothes. The real Weaver's pop top pops up in Half Moon Street (1986). She is stark naked in stark light playing a part-time prostitute. To celebrate turning fifty, flab-free Sigourney stripped down to actual bush in A Map of the World (2000), showing off a physique that is still capable of blowing out all the candles.
