The actress breaks down the emotional toll, practical effects and how co-star Inde Navarrette’s unsettling transformation pushed the film into darker territory
Megan Lawless had to dig deep to pull off Sarah’s climactic moment in director Curry Barker’s horror thriller Obsession. In a new interview, the actress opens up about the emotional and physical demands of that final sequence, while also praising the film’s visceral approach to scares and the fearless work of her co-star Inde Navarrette.
Obsession spins a cautionary tale about a wish gone horribly wrong, with Lawless’s character Sarah at the emotional center. She’s a layered, vulnerable woman whose unresolved feelings drive the film’s psychological stakes. According to Lawless, that complexity makes Sarah’s ending feel both inevitable and tragic—a grim reminder of what obsession can cost.
“Sarah is caught between romantic hope and the reality of what’s happening around her,” Lawless explains. “Her fate raises real questions about desire and its consequences.”
Filming Sarah’s last scene required meticulous choreography and genuine emotional commitment. Lawless describes the challenge of balancing graphic imagery with authentic character reactions, ensuring the audience feels the weight of the moment rather than just recoiling at the shock.
“The key was grounding the horror in character truth,” she says. “That’s what kept Sarah human, even as things got extreme.”
The production leaned heavily on practical makeup and effects work rather than relying on digital tricks. Lawless credits the effects team for creating prosthetics so convincing that actors could react to real textures and movements on set—producing performances that feel earned rather than manufactured.
“When you’re working with something tangible, your reaction is genuine,” Lawless notes. “That tactile quality makes the horror hit harder.”
What really shifted the film’s tone, Lawless says, was Inde Navarrette’s committed performance as Nikki. In a particularly chilling choice, Nikki deliberately alters her appearance to mirror Sarah—a move that deepens the film’s exploration of identity and obsession while making her character both sympathetic and terrifying.
“Inde went all in,” Lawless says. “That transformation added a psychological layer that made everything darker.”
Throughout production, Barker guided his cast through tonal shifts from dark comedy to full-scale horror while keeping character motivations grounded. Lawless describes a collaborative atmosphere where actors and crew worked in sync to ensure every scare emerged from character decisions rather than empty spectacle.
“Curry created space for us to find the truth in these extreme moments,” she says. “That’s what separates this from standard horror.”
For Lawless, Sarah’s brutal fate is emotionally necessary—a stark illustration of the film’s central warning about the cost of unchecked desire. She hopes audiences will connect with Obsession not just for its scares, but for what it has to say about longing, identity, and the choices we make.
“This ending had to feel real,” she concludes. “It had to matter.”
