How Alien: Romulus’ New Xenomorph Pays Tribute To Past Movies

This isn’t the first time a human hybrid version of the xenomorph has made it to the silver screen. InAlien Resurrection’s ending, a human hybrid is made by a clone of the Alien Queen with the help of human DNA. The hybrid in this film looks more like a xenomorph, with a human face at the end of an elongated head. While there are similarities, including a tall, skinny body,the human hybrid inAlien: Romulusmore resembles the Engineers fromPrometheusandAlien: Covenant, which is probably due to the black goo used to make the monstrosity.

Álvarez even confirmed directly that he was pulling fromPrometheusandAlien: Covenant’s mythology for the xenomorph-human hybrid inRomulus' ending.

The sudden appearance of the offspring inAlien: Romulusmay feel familiar, especially to the ending of the originalAlien. Álvarez has essentially recreated the famous ending of the original film with his own twist, as in theend ofAlien, Sigourney Weaver’s Ripley is seemingly far away from trouble in the escape pod when it’s revealed that the xenomorph is onboard. The end of Álvarez’s film plays out similarly, where Rain, Andy, and Kay seem to be out of harm’s reach until Kay gives birth to the offspring.

Who Plays Alien: Romulus' Human Alien Offspring & How Tall He Is

Alien: Romulus introduces a new human alien hybrid through Kay, and here’s who plays her offspring and how tall the actor is in real life.

This ending has been the hot topic of many discussions, splitting those who didn’t enjoy it and those who did in half. The former speak of an absurd ending and creature design that reminds them of what they consider to be the two lesser films of the franchise (PrometheusandAlien: Covenant), whilethe latter applaud the nightmarish design of the offspring and the twist of an already remarkable, visceral film. Álvarez’s video is a delectable treat to thefans ofAlien: Romulus, providing a look into the practical effects and hard work that went into making the film.
