Mutants, killer robots, primal warriors, alien worlds to rival Avatar, and a 1,000-year time jump: René Laloux's 1987 animated feature Gandahar has all the pieces of a cult sci-fi classic. And maybe it would hold that status if a pristine version of this psychedelic odyssey was easier to watch.

Thankfully, that changes later this summer, when Janus Films re-releases the original uncut Gandahar to U.S. theaters with a newly restored 4K transfer. Polygon is thrilled to unveil the first trailer for Janus’ 4K re-release in anticipation of the August release. If you thought the shape-shifting assassins and psychic babies of Dune Part 3 would be the trippiest experience you have in a multiplex this year, maybe buy your Gandahar tickets now. Here’s the official synopsis:

In a distant world, a merciless army of automata attacks Gandahar, turning its peace-loving people to stone. Hoping to discover the source of these Men of Metal, a council of matriarchs enlists the brave yet inexperienced warrior Sylvain (Pierre-Marie Escourro), who, while journeying through his planet’s outer regions, teams up with the Deformed, a race cast out from Gandahar after failed science experiments rendered them mutants. Soon, Sylvain learns that a gargantuan brain called Metamorphis (Georges Wilson) is responsible for his utopian society’s strife and—together with the beautiful Airelle (Catherine Chevallier)—travels through time to defeat him, in the process risking their lives and Gandahar’s very existence.

Laloux is perhaps best known for his 1973 animated film Fantastic Planet, a staple of weirdo DVD closets that got a worthy Criterion release nearly a decade ago. The filmmaker’s path to Accomplished French Sci-Fi Auteur was winding: he started out as a woodcarver, then eventually made short films with the help of psychiatric patients while working as a counselor. Fantastic Planet was his career breakthrough, while Gandahar, adapted from a novel by Jean-Pierre Andrevon, marked his final feature.

As Cinetantasique noted in 1988, Gandahar didn’t make much of a splash in its day, and was even more of a drip when it was ported to U.S. theaters (in a translated version overseen by none other than Isaac Asimov and Harvey Weinstein). From there, without the reverence that surrounded Fantastic Planet, Gandahar languished in smaller corners of the home video markets; technically you can watch it in 4:3 with the English dub right now on Prime Video. Technically.

Personally, having seen that version, I would hold out for the 4K release: what Janus has done for this visionary work will eclipse the crummy ripped-from-VHS quality you can experience this second. And with Laloux, the eye-popping visuals are 90% of the reason to show up — the other 10% is watching alien beings with faces in their chests yammer on about space politics. Fact: Laloux put a woman with four breasts (with two more on her knees) years before Total Recall. The guy had an imagination.

Gandahar opens on Aug. 28 in New York City, with a national rollout to follow.
