Stargate is a science-fiction screen franchise that began with Roland Emmerich and Dean Devlin’s 1994 film. Its defining technology is an ancient, ring-shaped portal that opens a wormhole to another Stargate, allowing people to travel between worlds. The television stories expand that premise into a connected universe of exploration teams, lost civilizations, and long-running series.
For a first viewing, start with the 1994 Stargate film, watch Stargate SG-1 through its 10-season run, then view the two SG-1 follow-up films, continue through Stargate Atlantis, and finish with Stargate Universe. You can alternate SG-1 and Atlantis for broadcast-era continuity, but you do not need to switch between episodes to understand the story.

What is Stargate?
The portal at the center of the franchise
The original Stargate, released in 1994, introduced a circular alien device capable of creating a wormhole to a matching gate elsewhere in the galaxy. That single idea supplies the franchise’s basic storytelling engine: a gate address can lead to another world, and each destination can reveal a different culture, danger, mystery, or piece of ancient history.
The film was directed by Roland Emmerich and co-written by Emmerich and Dean Devlin. The television continuation changes the emphasis from a single expedition to an ongoing Earth-based exploration program. Teams use the Stargate to reach other planets, gather information, and deal with the consequences of opening routes beyond Earth.

How television expands the concept
Amazon MGM’s franchise guide describes the three principal live-action series by their central missions:
- Stargate SG-1 follows an Earth military exploration team.
- Stargate Atlantis follows the search for the Ancients’ lost city.
- Stargate Universe follows a multinational group stranded aboard the Ancient ship Destiny.
Those premises make the shows connected without making them interchangeable. SG-1 is the foundation and the longest-running branch. Atlantis develops a related expedition in a different setting, while Universe moves the story onto a ship whose mission and circumstances create a more isolated form of exploration.
What the franchise is not
There is no single television series called simply Stargate. The name refers to a franchise made up of one theatrical film, several live-action series, two direct-to-video films, an animated series, and a later prequel web series. A viewer can follow the central live-action continuity without watching every entry.

| Stargate: The Ark of Truth | 2008 | Direct-to-video film | Continues the SG-1 story after its television finale |
| Stargate: Continuum | 2008 | Direct-to-video film | Another post-series SG-1 film |
| Stargate Universe | 2009–2011 | Two-season live-action series | Multinational team aboard the Ancient ship Destiny |
| Stargate Origins | 2018 | Prequel web series | Takes place in 1939, decades before the original film |
The official franchise guide lists SG-1, Atlantis, Universe, Origins, and Infinity as part of the broader screen franchise. The two 2008 films are specifically continuations of SG-1, rather than new series branches.
The best first-time Stargate watch order
This is the most practical route for a new viewer. It introduces the premise in release order, prioritizes the central live-action arc, and leaves optional material until you know whether you want more.
- Watch Stargate (1994). It establishes the ring portal, wormhole travel, and the setting that the television stories expand.
- Watch Stargate SG-1 seasons 1–7. These seasons build the main television continuity and the Earth exploration team at its center.
- Choose how to handle the overlap with Atlantis. For the simplest experience, continue through SG-1 seasons 8–10 without switching shows. For broadcast-era continuity, alternate the later SG-1 seasons with Atlantis seasons 1–3. You can use season blocks rather than alternating every episode.
- Watch The Ark of Truth after the SG-1 finale. The film follows the television ending and takes place before the Atlantis season-three finale.
- Watch Continuum. It is the other direct-to-video film that continues the SG-1 branch.
- Finish Stargate Atlantis. If you used the simple route, watch its five seasons after the main SG-1 run and films. If you used the continuity route, complete the remaining Atlantis episodes after placing The Ark of Truth before the season-three finale.
- Watch Stargate Universe seasons 1–2. This is the final major live-action branch in the recommended first-watch path.
The sequence is a viewing recommendation, not an official requirement. GateWorld’s September 2024 optimized order provides a more detailed interleaving plan for viewers who want to reproduce the original broadcast flow precisely.

Why start with the 1994 film?
Stargate Origins is chronologically earlier because it takes place in 1939, but it was released in 2018 and assumes interest in the established franchise. The 1994 film is the clearest entry point because it presents the device and the basic premise before any television branch builds on them.
Do you need to alternate SG-1 and Atlantis?
No. The overlap matters mainly to viewers who want the rhythm of the original broadcast period and the most continuity-conscious placement of crossover-era events. Finishing SG-1 first is easier to track, and it does not prevent you from understanding Atlantis. Alternating every episode adds scheduling work without being necessary for a first viewing.
Release order, continuity order, and completionist order
Different watch orders solve different problems. Pick one before you begin instead of changing plans every time a new title appears.
| Approach | Recommended sequence | Best for | Trade-off |
|---|---|---|---|
| Simple first watch | 1994 film; SG-1 seasons 1–10; the two SG-1 films; Atlantis; Universe | Most viewers who want a clear path | Does not mirror the original broadcast overlap |
| Broadcast-conscious | 1994 film; SG-1 seasons 1–7; alternate later SG-1 and Atlantis season blocks; place The Ark of Truth before the Atlantis season-three finale; finish both branches, then Universe | Viewers who care about continuity and release-era pacing | Requires tracking two shows at once |
| Chronological/prequel-first | Origins (1939), then the 1994 film and the live-action series | Completionists who want the earliest in-universe setting | Starts with a later-made prequel instead of the franchise’s original introduction |
| Completionist screen route | Core live-action path plus Origins and Infinity | Viewers who want every listed screen branch | The animated series and prequel are optional additions, not prerequisites for the main arc |
How the timeline fits together
1939: Stargate Origins
Origins is the earliest-set screen entry. Its story begins in 1939, long before the 1994 film, so it can be placed first in a strictly chronological experiment. Its late release makes it better treated as an optional prequel than as the default introduction.
1994: the original film
The film supplies the foundational premise: an ancient ring-shaped gate creates a wormhole to another Stargate. Every major live-action branch grows from that concept.
1997–2007: Stargate SG-1
SG-1 is the central television spine, running for 10 seasons. It turns the film’s setup into an ongoing Earth military exploration program.
2004–2009: Stargate Atlantis
Atlantis launched while SG-1 was still running and lasted five seasons. Its focus is the search for the Ancients’ lost city, which is why its broadcast-era placement overlaps the later SG-1 seasons.
Rank #3
2008: the two SG-1 continuation films
The Ark of Truth and Continuum are direct-to-video films made for the SG-1 branch. The Ark of Truth follows the series finale and must be placed before the Atlantis season-three finale if you are preserving that continuity relationship. Continuum is another follow-up film to SG-1.

2009–2011: Stargate Universe
Universe ran for two seasons and follows a multinational team aboard the Ancient ship Destiny. It is a distinct live-action branch and is easiest to watch after the earlier series.
What each major branch contributes
Stargate SG-1: the foundation
Choose SG-1 when you want the longest exploration of the franchise’s central premise. Its 10-season run provides the most extensive introduction to the Earth team, the gate network, and the recurring continuity that later live-action stories build around.
Stargate Atlantis: a related expedition
Atlantis is the natural next step after becoming familiar with SG-1. Its five seasons shift attention to the search for the Ancients’ lost city while remaining part of the same broad live-action franchise.
Stargate Universe: a shipboard survival story
Universe changes the scale and situation again. The story follows a multinational group aboard Destiny, an Ancient ship, and works best after the viewer understands the earlier exploration framework.

The Martin Gero project
Amazon MGM originally announced a new Stargate series with Martin Gero as showrunner and Brad Wright and Joseph Mallozzi as consulting producers. In that announcement, Gero said: “I spent five years at the franchise working across all three series, Stargate taught me everything about making television—it’s written into my DNA,” Martin Gero, showrunner and executive producer.
That announcement is no longer a reliable statement of the project’s current status. On June 3, 2026, Space.com reported that Amazon had decided not to move forward with the Gero project. The report attributed the decision’s alleged reasoning to an unnamed Variety source. Joseph Mallozzi publicly disputed the broad-appeal explanation, so that rationale should not be presented as established fact.
The unconfirmed Jac Schaeffer claim
A fan-run #SaveStargate press page updated October 11, 2026 claims that Amazon MGM announced a new series with Jac Schaeffer on October 10. The page says the campaign is unofficial and is not affiliated with Amazon MGM. Without an official studio announcement or independent confirmation, that claim is not enough to call a new series confirmed.

Where to watch and how to own the series
Streaming availability
Streaming catalogs change by country, licensing window, and date. Amazon’s franchise guide includes Prime Video watch links, and a Prime Video listing for Stargate SG-1 season 10 has appeared, but neither establishes that every film and season is available in every territory. Search the title in your local service catalog immediately before starting, especially for the two direct-to-video films and the less commonly listed branches.
If a service shows only selected seasons, use the table above to identify what is missing before you begin. A partial catalog can make a release-order plan difficult if you assume the entire franchise is hosted in one place.
Physical Blu-ray options
Visual Entertainment lists The Stargate Blu-ray Collection, combining SG-1, Atlantis, and Universe, along with separate complete-series Blu-ray sets. The distributor describes the collection as containing 17 seasons and hundreds of episodes. Those figures describe the contents of the boxed set, not audience size or popularity.

Books and other supplementary material
Fandemonium’s order form lists SG-1 novels, Atlantis novels, and short-story anthologies. Treat these as supplementary reading rather than required screen canon. They are useful only after you have decided that you want more material beyond the filmed continuity, and current stock or retailer availability should be checked before buying.
A practical checklist before you start
- Decide whether you want the simple route or broadcast-era interleaving.
- Start with the 1994 film unless you deliberately prefer the 1939 prequel setting.
- Plan access to all 10 SG-1 seasons before beginning; switching services halfway through can interrupt the continuity.
- Mark The Ark of Truth as a post-SG-1 film that belongs before the Atlantis season-three finale.
- Keep Continuum with the SG-1 follow-up films rather than treating it as a separate television season.
- Leave Infinity and Origins for later unless your goal is to see every listed screen entry.
- Verify your local streaming catalog or Blu-ray region before committing to a viewing schedule.
- Do not treat unconfirmed announcements as part of the available franchise library.
Bottom line for new viewers
The most approachable Stargate path is the 1994 film, Stargate SG-1, the two SG-1 continuation films, Stargate Atlantis, and then Stargate Universe. Alternate SG-1 and Atlantis only if matching the broadcast-era continuity matters to you. Add Origins and Infinity afterward as optional branches, and verify local streaming or disc-region availability before you begin.
