In just a few weeks, Terrence Malick will begin production on his new World War II drama Radegund — but it won’t be the last time we hear about the director this year. Along with recently finishing work on his Austin-set drama Weightless — which won’t get a theatrical release until 2017, but may show up at a film festival in the fall — his long-gestating documentary Voyage of Time will arrive in just a few months.

Earlier this summer, IMAX let slip that they’ll give the film a release on October 7, and now they’ve updated their official site with a new synopsis and confirmed a runtime, along with the release date. This version (Voyage of Time: The IMAX Experience) clocks in at 40 minutes with narration from Brad Pittt and the synopsis lets us learn a bit more about the project, which they say is his “most original film to date.” Meanwhile, there’s no word yet from Broad Green if the expanded, Cate Blanchett-narrated, 90-minute companion feature Voyage of Time: Life’s Journey, will arrive around the same time, but they call it a “poetic and provocative ride full of open questions.”

Check it out below, along with the poster from Indiewire, as we await the first trailer.

Voyage of Time: The IMAX Experience is a one-of-a-kind celebration of life and the grand history of the cosmos, transporting audiences into a vast yet up-close-and personal journey that spans the eons from the Big Bang to the dinosaur age to our present human world … and beyond. A labor of love from one of American cinema’s most acclaimed and visually exciting filmmakers, Terrence Malick (The Thin Red Line, The Tree of Life), Voyage of Time has been nearly four decades in the making and represents the filmmaker’s first foray into documentary storytelling. The film’s panorama of awe-inspiring images will take you into the heart of monumental events never witnessed — from the birth of the stars and galaxies to the explosion of diverse life-forms on planet earth, including humankind — in immersive new ways that only IMAX can deliver. This is a cosmic experience — a hymn to the glories of nature, life and scientific discovery — in which all the elements come together to form Malick’s most original film to date. Voyage of Time: The IMAX Experience, a 40-minute, giant-screen adventure narrated by Brad Pitt, which immerses audiences directly into the story of the universe and life itself, will be shown exclusively in IMAX® theatres.

Voyage of Time: The IMAX Experience opens on October 7.
