Every Main Cast Member of Alien: Romulus
Cailee Spaeny - Rain
Cailee Spaeny brings the franchise's new protagonist, Rain, to life in Alien: Romulus.
Rain is a young miner who wants to leave Jackson's mining colony alongside her brother, Andy, and head to Yvaga III. However, her transport request is denied.
Desperate to get off the planet, Rain agrees to join Tyler's crew in retrieving highly graded cryo chambers in an abandoned space station, but what they discover are facehuggers and a hive of Xenomorphs instead.
Rain, armed with her bravery, leads the crew in the clash against the Xenomorphs, using her wit and skill to outlast their extraterrestrial enemies.
Spaeny is best known for playing roles in Pacific Rim: Uprising, Priscilla, and Civil War.

David Jonsson - Andy
David Jonsson stars as Andy, Rain's brother who is an android tasked to protect his sister and do what's best for her no matter what.
As a synthetic, Andy becomes useful in accessing a good chunk of the space station's control using the module from an incapacitated android aboard the location.
Doing this temporarily makes Andy an android who is loyal to the company (aka Weyland-Yutani Corporation), meaning that his prime directive is to do whatever is necessary to bring the creature back into the colony even if it means abandoning his crew.
Jonsson's most recognizable role is playing Gus Sackey in Industry. The actor also appeared in Deep State, Endeavour, and Murder Is Easy.
