There’s a detail buried in the character breakdown for Na Hong-jin’s “Hope” that recontextualizes the entire cast list: Michael Fassbender, Alicia Vikander, Taylor Russell and Cameron Britton aren’t playing humans at all. They’re the threat.
That reveal came alongside the film’s very first poster, an image Deadline described as a moment of a rider on horseback seizing a young man by the collar in the depths of a forest, saving him as he’s pursued by something unseen. The production explained the poster captured a young man running from an alien threat before being pulled to safety — and confirmed, for the first time, that Fassbender, Vikander, Russell and Britton would be playing the aliens themselves, opposite a core Korean cast led by Hwang Jung-min, Zo In-sung and Hoyeon.
A Divide Built Into the Casting
The choice to split the cast that way wasn’t incidental. ZAPZEE reports that Na deliberately cast Korean actors as the residents of the film’s fishing village, Hopo Port, while reserving the international stars for the extraterrestrial characters — a structural choice meant to visually and narratively underscore the divide between the townspeople and the outsiders threatening them.
The alien characters aren’t interchangeable, either. Per Wikipedia’s cast listing and ZAPZEE’s interviews with the cast, Fassbender and Vikander play members of an alien royal family, Russell plays a character named Maya Harper, also identified as the maidservant Aidobor in some materials, while Britton portrays Bamigir, a lower-ranking alien who is the first of his kind to reach Hopo Port. Deadline’s Cannes coverage goes further, reporting that Fassbender, Vikander and Russell specifically play key members of the royal family of a planet called Gh’ertu, with the alien ensemble representing a range of shapes and class distinctions from their world — suggesting the aliens have their own internal hierarchy playing out alongside the human story.

What the Actors Have Said
The cast has been fairly open about how unusual the assignment was. Britton told ZAPZEE it felt both unique and challenging to play a character whose entire existence revolves around survival, while Russell — who won Venice’s Marcello Mastroianni Award for “Bones and All” — explained that the film’s mysterious premise immediately caught her attention because she had never encountered a project quite like it.
Vikander and Fassbender, a real-life couple, both pointed to Na’s earlier film “The Wailing” as the reason they signed on. At the Cannes press conference, Vikander said simply that she fell in love with Asian cinema and didn’t hesitate to say yes once she was approached. Fassbender’s explanation was shorter: “Alicia told me to do it.”
The alien roles were shot using motion capture and facial capture technology while the cast filmed in Korea, a production approach ZAPZEE notes was intended to give the extraterrestrial characters detailed backstories and real emotional weight rather than treating them as faceless monsters.
Reading Between the Lines
Fan and critic speculation has leaned into exactly what the poster and character reveals implied. Fangirlish points out that Fassbender is listed last in the film’s billing — typically a sign of a bigger role than his screen time might initially suggest — and floats the theory that his character could be connected to whatever organization or hierarchy is driving the aliens’ arrival at Hopo Port in the first place.

That framing lines up with how the plot has been described elsewhere. According to Variety, the story kicks off when police chief Bum-seok (Hwang Jung-min) and officer Sung-ae (Hoyeon) are sent to investigate a mysterious creature terrorizing Hopo Port, while a group of local hunters led by Sung-ki (Zo In-sung) tracks the same threat independently from the surrounding forest — setting up parallel human storylines that eventually collide with the alien royal family’s own internal conflict.
Where the Film Stands Now
“Hope” premiered in competition at this year’s Cannes Film Festival, where it reportedly received a seven-minute standing ovation, according to Deadline’s Cannes report. Neon picked up North American, U.K. and Australian distribution rights ahead of that premiere and released the film’s first trailer this summer, with the movie opening domestically on September 9 — positioning it as one of the counter-programming options against the rest of that fall’s blockbuster slate.
It marks Na’s first film since 2016’s “The Wailing,” and according to ComicBookMovie’s Cannes coverage, the director has already floated the idea of a sequel as a real possibility, depending on how the story’s alien-human divide is received by audiences.
