Romulus Cast & Character Guide

Alien: Romulus boasts an impressive cast of up-and-coming stars. The cast includes actors who’ve been headlining recent blockbusters to fresh faces who could become tomorrow’s biggest stars. Set chronlogicaly between the events of Alien and Aliens, the film follows a group of six young adults as they try to scavenge supplies for a lengthy cosmic trip from a derelict space station. However, they’re unaware the station is abandoned and in ruins because of the creatures trapped aboard, and they’re more than eager to lash out at any visitors.

One of the often overlooked strengths of Alien was the way the film bucked traditional sci-fi castings and instead focused on a diverse collection of actors that brought a grounded humanity to their performances. This is something Alien: Romulus looks to replicate, keeping much of the film’s focus centered solely on the central cast of six young adults trying to make their way across the cosmos to a brighter future. Here’s the cast of Alien: Romulus and where else you’ve seen them.
