While Alien: Romulus told an entirely new story nestled in between two classic films — Alien (1979) and Aliens (1986) — it still managed to reference quite a bit of lore and detail from the entire franchise. While the existence of the Xenomorphs themselves hardly counts as Easter eggs, the return of Ian Holm’s visage, this time as a new android named Rook, certainly helped to cement Romulus as a vibrant part of the Alien chronology, even if Rain and Andy’s adventure is, on some level, a side quest.
But, it turns out there’s a much deeper, and more interesting Easter egg hidden in plain sight in Romulus — Ellen Ripley (Sigourney Weaver) is technically in this movie! But because Ripley is in hypersleep for several decades between Alien and Aliens, how does this work?
