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 Prometheus (2012), set in 2093.
- 16 years after Alien: Covenant (2017), set in 2104.
- 2 years before Alien - O 8º Passageiro (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 Aliens: O Resgate (1986) and Alien 3 (1992), both set in 2179.
- 261 years before Alien - A Ressurreição (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 - O 8º Passageiro (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.
