For over 40 years, the Xenomorph has terrorized audiences with seven films, two Alien vs. Predator crossover movies and a show, Alien: Earth. The prequel, which premiered on FX and Hulu on Aug. 12, 2025, marked the first time the story has been adapted for the small screen.

"Alien: Earth" is Noah Hawley's latest silver-to-small screen project. But if you want to watch all the film entries which preceded it, here's what you need to know.

Alien: Earth is also uncharted territory for the franchise, bringing the Xenomorphs to home turf for the first time (the end of Resurrection doesn’t count). So, with the show kicking off on Hulu and Disney Plus, this is what you need to know about the timeline.
