With his 2012 riff on the Alien universe Prometheus, Ridley Scott discovered that fans of the franchise are picky. Beautiful as that film is to look at, they also want the stories to make sense. Prometheus was heavily criticized for not making any.
Scott's newly-released short film "The Crossing" is about the journey of the remaining characters at the end of Prometheus, Elizabeth Shaw (Noomi Rapace) and Michael Fassbender's treacherous android David. In it, Scott has effectively formed a bridge between that film and the upcoming Alien: Covenant—which makes sense because it's also the "official prologue" to that film.
"After we made contact with the Engineers," David narrates, "the Prometheus was destroyed. All hands were lost, but I escaped with Elizabeth in one of their ships." He goes on to describe her compassion in reassembling him—but we don't know her ultimate fate.
Perhaps we'll learn just what happened to Shaw when Covenant, its cast featuring Fassbender, Katherine Waterston, Billy Crudup, Danny McBride, Demián Bichir, and Carmen Ejogo, premieres on May 19.
