Get your bronze armor ready, because Knights of the Zodiac is back in the spotlight — this time with a live-action movie that, although it was a box office failure, is winning over audiences on streaming. Released worldwide in cinemas in 2023, the film didn’t reach the expected success but found a new life in the Prime Video catalog, where it surprises with high viewership numbers.
In this TVStreamzilla article, you’ll understand the path this production took, the challenges it faced, what’s behind its rediscovery on streaming, and what this might mean for the franchise’s future. So, get ready to dive into the universe of Seiya and the Knights of Athena!
About the Knights of the Zodiac live-action
The movie Knights of the Zodiac — its official international title — was released worldwide with the bold mission to adapt the famous anime and manga by Masami Kurumada into a live-action film. The production was directed by Tomasz Baginski, featured elaborate visual effects, and starred an international cast led by Mackenyu (Seiya), Madison Iseman (Sienna/Athena), Famke Janssen, Sean Bean, and Mark Dacascos.
Despite the nostalgic appeal and the effort to adapt such a beloved material, the film faced negative reviews. With weak box office performance, it grossed just over 7 million dollars worldwide — a low figure compared to the investment.

A new chance on Prime Video
After its cinema run, the movie arrived on Prime Video’s catalog. To everyone’s surprise, it became one of the most-watched titles on the platform. The production found a new audience — especially old anime fans who hadn’t seen it in theaters and those curious about adaptations of major Japanese franchises.

This streaming success shows how audience behavior can vary by platform. While competition and criticism weighed heavily in theaters, streaming’s easy access and nostalgia made all the difference.
What to expect from the movie?
The live-action retells the origin of Seiya, an orphan who discovers he is the reincarnation of the Pegasus Knight. He must protect the goddess Athena in her human form, Sienna. The script condenses several elements from the original arc, focusing on the formation of the Knights and the looming threat to the young goddess.
Although the pacing and some changes from the original material sparked criticism, the film delivers choreographed action scenes, convincing special effects, and a clear attempt to westernize the mythology of the Knights for a broader audience.
