When August 1, 2026 arrives, a swath of Stargate enthusiasts will notice a noticeable gap in their Prime Video catalog. On that date, Amazon will remove three cornerstone titles: the 1994 feature film Stargate, the digital series Stargate Origins: Catherine, and the direct‑to‑video film Stargate: The Ark of Truth.

The purge follows a long‑standing practice of periodic catalog refreshes that streaming services use to honor and renegotiate licensing agreements. According to the source, the original film—an ambitious blend of ancient Egyptian imagery and military science‑fiction—will be the first to depart. Origins: Catherine, which traces the early days of the Stargate program, and The Ark of Truth, the film that resolves a lingering threat from the SG‑1 era, are scheduled to leave the platform on the same day.

The 1994 movie, directed by Roland Emmerich and co‑written with Dean Devlin, opened the franchise with a theatrical release on October 28, 1994 by Metro‑Goldwyn‑Mayer. It earned $196.6 million worldwide against a $55 million budget, a result that set the stage for a sprawling franchise that would expand into television, animation, and direct‑to‑video projects.

Stargate Origins: Catherine offers a glimpse into the program’s embryonic phase, while The Ark of Truth concludes a storyline that began in the popular Stargate SG‑1 series. Both works had been part of Prime Video’s library for years, providing fans with complete narrative arcs that tie directly into the larger mythos.

Despite these departures, Prime Video still hosts the core television lineup. The ten‑season Stargate SG‑1, the series that broadened the film’s mythology, remains fully available. Stargate Atlantis, which transports the action to the Pegasus galaxy, and Stargate Universe, the more serialized entry that follows a crew aboard the alien vessel Destiny, are also on the platform.

A notable exception is Stargate: Continuum, a direct‑to‑DVD feature that explores time‑travel. The source notes that this title is not slated for removal, an anomaly that has sparked discussion among fans about the intricacies of licensing agreements.

Industry observers point out that catalog titles often cycle between providers. When a title exits one service, it can reappear on another platform within months, sometimes reaching a broader audience. The source reports that fans are monitoring announcements from competitors such as Netflix, Hulu, Tubi, and Pluto TV for potential new homes for the departing titles.

The removal of the original film and the two related titles may affect viewers who rely on Prime Video for convenient binge‑watching, especially during the summer months when many households turn to air‑conditioned marathons. However, the continued availability of the main series ensures that both new and long‑time fans can still follow the primary narrative arcs.

As the August 1 deadline approaches, the community remains hopeful that the displaced titles will find new streaming platforms. The source suggests that the franchise’s proven track record of dedicated viewership and its status as a science‑fiction staple make it an attractive candidate for other services looking to capitalize on nostalgic demand.

In summary, Amazon Prime Video will discontinue the 1994 Stargate film, Stargate Origins: Catherine, and Stargate: The Ark of Truth on August 1, 2026. The core television series—SG‑1, Atlantis, and Universe—remain available, and Continuum is not scheduled for removal. Fans and industry watchers are watching closely for announcements from rival streaming services that may acquire the departing titles.
