Though Ridley Scott is a credited producer, Noah Hawley revealed that his involvement was limited, due to his preoccupation with other projects. Hawley said, "In the course of making a single season of television, that 87-year-old man made three or four huge films." Producer David W. Zucker added, "the last thing [Scott is] interested in doing is getting in front of another filmmaker's vision."
The series takes place in 2120, meaning that it's set:
- 27 years after Prometeo (2012), set in 2093.
- 16 years after Alien: Covenant (2017), set in 2104.
- 2 years before Alien, el octavo pasajero (1979), set in 2122.
- 17 years before Alien: Isolation (2014), set in 2137.
- 22 years before Alien: Romulus (2024), set in 2142.
- 59 years before Alien 2: El regreso (1986) and Alien³ (1992), both set in 2179.
- 261 years before Alien La resurrección (1997), set in 2381.
Hawley started production on the first episode while the 2023 Writers and Actors' strikes were happening, so he could only film scenes with non SAG-AFTRA performers.
Series creator and showrunner Noah Hawley confirmed that if Alien: Earth is a hit, he sees a day, perhaps several seasons down the road, when its events might directly connect to the events of Alien, el octavo pasajero (1979).
With a budget north of $250 million for its first season, Alien: Earth is the most expensive show ever broadcast on American cable television.
