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.

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.
