For a first viewing, watch the seven core films in release order: Alien, Aliens, Alien 3, Alien: Resurrection, Prometheus, Alien: Covenant, and Alien: Romulus. For chronological story order, use Prometheus, Alien: Covenant, Alien, Alien: Romulus, Aliens, Alien 3, and Alien: Resurrection. Release order best preserves the series' revelations and changing styles. Chronology works better for returning viewers who want to follow the fictional history from the prequels through Ripley's era.

Alien movies in release order
The core series contains seven films. The two Alien vs. Predator crossovers form an optional branch, bringing the broader movie count to nine. This order lets each film introduce its ideas when audiences originally encountered them.
It also makes the major shifts clear: Alien is controlled survival horror, Aliens expands into military action, and the later prequels explore the mythology behind the threat. Prometheus and Alien: Covenant appear late because they were produced as prequels. Alien: Romulus is the newest released film, although its story belongs between Alien and Aliens. The official Disney+ watch guide confirms this seven-film release sequence.
- Alien (1979)
- Aliens (1986)
- Alien 3 (1992)
- Alien: Resurrection (1997)
- Prometheus (2012)
Alien movies in chronological order
Chronological order follows events inside the fictional universe rather than theatrical release dates. The placement of Romulus is the detail most likely to cause confusion.
Its young characters have a separate story, but the abandoned-station plot connects the aftermath of Alien with the corporate and biological threats developed elsewhere in the series. The chronology is straightforward once the crossovers and television series are removed. Hulu's franchise timeline places Romulus between Alien and Aliens and identifies the years used above.
- Prometheus — opens in 2089, with its main expedition occurring later
- Alien: Covenant — 2104
- Alien — 2122
- Alien: Romulus — 2142
- Aliens — 2179
Which viewing order should you choose?
Choose release order if you are new to Alien. The prequels explain or reinterpret mysteries that the original film presents without answers, so starting with them changes how those mysteries land.
Choose chronological order for a rewatch or a mythology-focused marathon. Prometheus and Covenant establish the Engineers, the android David, and the corporate world before the Nostromo crew encounters the series' central creature. For a shorter introduction, choose one of these three-film routes: Alien: Resurrection is necessary for the complete Ripley storyline, but its large time jump makes Alien 3 a natural stopping point for a shorter marathon.
- Classic Ripley arc: Alien, Aliens, Alien 3
- Modern bridge: Alien, Alien: Romulus, Aliens
- Prequel story: Prometheus, Alien: Covenant, Alien
- Release-conscious sampler: Alien, Aliens, Alien: Romulus
Where do the crossovers and Alien: Earth fit?
AVP: Alien vs. Predator (2004) and Aliens vs. Predator: Requiem (2007) are optional crossover films. Neither is required to understand the seven-film Alien storyline. In crossover release order, place them after Alien: Resurrection and before Prometheus.
In their own story chronology, watch Alien vs. Predator first and Requiem second; both occur in the present-day portion of that branch, long before Prometheus. Alien: Earth is a television series, not an eighth core movie. Its story is set in 2120, between Alien: Covenant and Alien, but adding it to a film marathon changes the pacing considerably. Treat it as a separate expansion unless you specifically want a screen-wide chronological watch.
Streaming checklist before you start
Streaming rights vary by country, plan, and month. Older guides may claim that the full saga is on one service even when the current catalog has changed.
In the United States, Hulu's public Alien collection currently identifies Alien: Romulus as available, but it does not display every core film. A current JustWatch franchise guide also shows the movies divided among several subscription services, with rental and purchase alternatives. Before starting the marathon:.
- Search each exact title in your country, rather than relying on a franchise landing page.
- Confirm that "watch" means included with your plan, not a rental, premium add-on, or live-TV package.
- Check whether your service offers the theatrical cut or an alternate edition.
- Add all seven films to one watchlist before watching the first.
- Use digital rental, purchase, or physical discs to fill catalog gaps.
