Obsession is swiftly turning into one of the biggest horror breakout stories of 2026. Directed by rising filmmaker Curry Barker, the unsettling psychological horror film has already earned strong reactions from critics, currently holding a 97% score on Rotten Tomatoes, an 83 Metacritic rating, and a 7.7/10 on IMDb.

The film follows Bear, a shy young man who makes a dangerous wish for his childhood friend Nikki to fall in love with him — only for things to spiral into disturbing territory when her behavior becomes increasingly terrifying. With Obsession now soon landing in theaters and drawing comparisons to modern horror standouts, many viewers are also paying closer attention to the cast behind the eerie story.

Curry Barker, who also wrote and edited the film, has already sparked comparisons to filmmakers like Jordan Peele and Zach Cregger thanks to Obsession’s blend of dark comedy, violence, and social horror themes.

But who exactly stars in this new unsettling horror film?

Michael Johnston as Bear: Michael Johnston leads Obsession as Bear, a shy and socially awkward music store employee, hopelessly in love with his childhood friend Nikki. After using a mysterious “One Wish Willow” to make Nikki love him, Bear finds himself trapped in a nightmare of his own making as reality begins unraveling around him. Johnston carries much of the film’s emotional and moral tension through a protagonist who is both sympathetic and deeply flawed.

Many viewers may also recognize Johnston from projects like Teen Wolf, where he played Corey Bryant.

Inde Navarrette as Nikki: Playing Bear’s longtime friend and eventual love interest, Nikki is Inde Navarrette, who delivers one of the film’s most unsettling performances. Nikki transforms from Bear’s grounded childhood friend into something increasingly disturbing after the wish changes her behavior, forcing Navarrette to balance emotional vulnerability with psychological horror.

Audiences may know Navarrette best for her role as Sarah Cushing in Superman & Lois.

Cooper Tomlinson as Ian: Cooper Tomlinson appears as Ian, one of the people within Bear and Nikki’s social circle who gradually begins noticing that something feels off about their increasingly strange relationship. As suspicions around Nikki’s sudden personality shift grow, Ian becomes part of the film’s mounting tension.

Megan Lawless as Sarah: Megan Lawless rounds out the main cast as Sarah, another member of the friend group caught in the emotional fallout surrounding Bear and Nikki. While operating more in the supporting ensemble, Sarah contributes to the growing concern among friends as Nikki’s behavior becomes harder to ignore.

What makes Obsession especially intriguing is how much of its horror depends on the cast, like any other horror film, which is heavily dependent on the performances, selling the film’s emotional weirdness before the chaos fully kicks in. Michael Johnston’s awkward, painfully relatable performance as Bear and Inde Navarrette’s unnerving switch between affection and terror give the movie much of its unsettling energy, while the supporting cast helps make the increasingly bizarre situation feel strangely believable.

5 Reasons Why ‘Obsession’ Is Becoming Horror’s Biggest Surprise Hit of 2026

But Obsession is not gaining attention only because of its cast — the film’s unusual premise and early critical reception have also turned it into one of horror’s biggest surprise success stories of the year.

Part of what has made Obsession stand out among horror fans is its unusual blend of romance, dark comedy, and psychological terror. What begins almost like a rom-com gradually transforms into a deeply unsettling horror story about obsession, consent, and emotional manipulation.

 Critics have also praised Barker’s willingness to tell the story from the perspective of someone making increasingly troubling choices, rather than positioning him as a straightforward hero. The film has also drawn comparisons to recent horror successes like Barbarian, Talk to Me and Weapons, further fueling interest in Barker as one of horror’s newest emerging voices.
