Alien: Romulus is the newest movie in the Alien franchise, telling the story of a brand-new group of characters who find themselves trapped aboard a spaceship trying to survive an attack by a group of Xenomorphs. Romulus is one of the best-reviewed films in the very long-running Alien franchise’s history, due to its storytelling, characters, and writing, but one aspect of the film that has garnered a lot of attention is the inclusion of Rook, a character who imitates the likeness of the late Ian Holm, who played Ash in the original film.
