Sigourney Weaver stars in Aliens, the sequel to the 1979 blockbuster Alien, reprising her role as Officer Ripley, the sole survivor of the spaceship Nostromo's encounter with a deadly extraterrestrial. This time she returns to the very planet where her nightmare originally began with a squad of heavily armed marines, in a search-and-rescue mission for some missing space colonists.
