‘Alien: Earth’ Exclusive: In FX’s Haunting Series, Everyone Can Hear You Scream

Hawley sets up a number of dualities like this in the story. Two others are the hard-liner Atom Eins (played by Adrian Edmondson, the Star Destroyer captain from The Last Jedi), who is the fixer and first lieutenant for Boy Kavalier, and the technician Arthur Sylvia (David Rysdahl, the hapless husband on Fargo, season five), the husband of Dame who starts to have misgivings about the Hybrid program he has helped create.
