Transformers One Rolls Onto Netflix Today: The Optimus Prime and Megatron Origin Story Is Finally Streaming

Transformers One, the animated origin story of Optimus Prime and Megatron, arrives on Netflix today, Thursday, October 15 — the first streaming home for a film that played theaters in the fall of 2024 and has been waiting on a service ever since. If it slipped past you on the big screen, today is the easy fix: the best-reviewed idea the franchise has had in years, one click away.

The premise is the one the franchise had never actually told on screen. Long before the war for Cybertron, Orion Pax and D-16 were miners — low-caste bots who haul the energon that keeps their world running and who dream, the way young men do, of being more than their assigned place. They were also friends bonded like brothers. Transformers One is the story of how that brotherhood formed, what the two of them found when they went looking for a better life on Cybertron’s surface, and how it broke into the rivalry between Optimus Prime and Megatron that defines everything after.

The voices behind the metal

Chris Hemsworth voices Orion Pax, the future Optimus Prime, opposite Brian Tyree Henry as D-16, the future Megatron — casting that underlines the film’s whole idea: these are young men, not yet legends or villains. Hemsworth plays Pax with a cocky, restless optimism a world away from the grave commander of the later films, while Henry gives D-16 a warmth that makes where he ends up land like a loss instead of a twist. Scarlett Johansson voices Elita-1, the no-nonsense commander both of them are trying to impress; Jon Hamm is Sentinel Prime, Cybertron’s gleaming leader; Laurence Fishburne brings the weight as Alpha Trion; and Steve Buscemi turns up as Starscream, already scheming. Behind the camera is Josh Cooley, who directed Toy Story 4, and it shows — this is a filmmaker who knows how to build a friendship first and let the spectacle grow out of it.

There is a shadow over the lead role, and the film knows it: Optimus Prime has been defined for decades by Peter Cullen’s voice. Hemsworth doesn’t imitate him. He plays the younger man Cullen’s Prime would have had to grow out of — louder, funnier, more reckless — and lets the authority arrive gradually, which turns out to be the whole arc of the movie in miniature.

Why this one connected

Transformers One was the franchise’s return to a fully animated theatrical feature — the first since the animated film of 1986 — and it took a different road from the live-action run: back to Cybertron, before Earth, before the war, with the Prime–Megatron split played as a fallen friendship rather than a standard hero-and-villain setup. The animation goes all-in on a painted, toy-shelf vibrancy instead of the live-action films’ chrome realism, and the story trusts a simple engine: two friends, one injustice, and a widening crack between what each of them thinks the answer is. Pax wants to fix the system from inside it. D-16 stops believing the system deserves fixing. Everything the franchise becomes grows out of that argument.

Critics were kind when it opened in September 2024, and the audiences who found it were kinder — but the theatrical run never quite matched the word of mouth. That is exactly the profile of a film that finds its real audience on streaming: too sincere for the summer pile-up, built to be rewatched, and impossible to describe to a friend without landing on the word “brothers.” Netflix has a good track record of giving animated films that second life, and this one arrives with a built-in event hook — it is landing the same day the service drops a new season of The Diplomat and Peacock launches Crystal Lake, and it is the one title on today’s slate the whole family can actually watch together.

Part of the pleasure is the world itself. Cooley’s Cybertron is a working society, not a backdrop: a gleaming capital on the surface, a mining underclass underneath it, and energon — the fuel everything runs on — treated the way rent and wages are treated in a company town. Pax and D-16 start the film as believers in that world, which is what makes the middle of the movie, a journey across a surface neither of them has ever been allowed to see, play like a proper adventure rather than a countdown to a foregone conclusion. There is a set-piece race through the capital, a train heist’s worth of momentum, and a steady drip of answers about why their world works the way it does — and every answer splits the two friends a degree further apart on the only question that matters: when you find out the game is rigged, do you fix it or burn it?

That is also why the film works as a starting point. Transformers One is a clean continuity reboot — no homework, no six-film syllabus, no homework-adjacent cartoon canon required. A kid meeting these characters for the first time and a lapsed fan who checked out somewhere around the third live-action sequel get the same movie: a complete story with a beginning, a middle and an end that happens to rewire forty years of franchise mythology into one friendship. It is rated PG and plays like it — the action is big, the stakes are emotional rather than gruesome — which makes it the rare title on this week’s slate that works as a whole-family press-play.
