The Ultimate Planet: A Sci-Fi Thriller About Lost Memories
Dima Khrust is an auto mechanic living an ordinary life—until an accident triggers something extraordinary. Suddenly, he's flooded with vivid memories of service on the mysterious Ninth Planet: alien landscapes, a human base, battles with monsters, and a woman named Polina he loved. The problem? His fellow soldiers don't remember any of it. No one else recalls the Ninth Planet at all. What's striking is that these aren't fragmented dreams or delusions—they're specific, tactile, lived-in memories that don't match anyone else's reality. According to Letterboxd's plot summary, Dima begins to suspect that someone has systematically altered the minds of everyone around him, erasing their recollection of what happened on that distant world. To uncover the truth—and to find Polina—he'll need to return to the planet itself, a place that's clearly far more dangerous than his fragmented memories suggest.
What We Know So Far
The Ultimate Planet is scheduled for theatrical release in Russia on September 24, 2026, with Central Partnership handling distribution. Directed by Nikolay Rybnikov and written by Igor Tkachenko, the film brings together an ensemble cast including Yura Borisov in the lead role, alongside Irina Starshenbaum, Aleksey Serebryakov, Maksim Emelyanov, Konstantin Beloshapka, and Igor Grabuzov. It's a co-production involving CTB Film Company, DixiMedia, Gazprom-Media, and the Cinema Foundation of Russia—a significant backing that signals ambition at the production level.
Genre-wise, don't expect a straight sci-fi film. The film blends drama, science fiction, action, and adventure into what appears to be a high-concept thriller with spectacle. The official trailer has already landed on Kinoafisha, confirming the visual scope and confirming its 2026 arrival.
Why This Matters
Russian science fiction cinema has been quietly building momentum. What's interesting—and honestly, what's kept me thinking about this one—is that the premise taps into something timeless: the unreliable narrator, the conspiracy, the question of what's real when your own mind becomes the crime scene. That's not new territory, but it's fertile ground, especially when paired with the scale of an alien world and the stakes of return.
Borisov, who carries this film, is known for nuanced, grounded work in contemporary Russian cinema. Pairing him with a high-concept sci-fi premise creates an interesting tension—you're not getting a typical action hero, but someone who has to convince us (and himself) that his memories matter even when everyone else has forgotten.
