Sofia Black-D'Elia
Emma Drakeford

Following the outbreak of a virus that wipes out the majority of the human population, a young woman documents her family's new life in quarantine and tries to protect her infected sister.
I’ve seen this trick before—the outbreak movie that promises gore but delivers something quieter. Viral, the 2016 horror-drama from Ariel Schulman and Henry Joost, is one of those films that sneaks up on you. It’s not about the parasite. It’s about the people who try to outrun it, and how quickly love curdles into something unrecognizable when the walls close in.
The directors, best known for Paranormal Activity 3 and Nerve, have a knack for turning everyday spaces into pressure cookers. Here, they take a suburban home—a place of homework and half-eaten dinners—and let it fester. The camera lingers on the mundane: a kitchen counter littered with cereal boxes, a hallway where sneakers are kicked off without care.
Then the parasite arrives, and suddenly every surface feels like a threat. That’s the real horror of Viral—not the creature itself, but the way it forces the characters to confront what they’re already carrying inside.

Sofia Black-D’Elia plays Emma, the older sister, a girl who’s spent her life being responsible. She’s the one who remembers to buy milk, who checks the locks at night, who answers the phone when their father is late. Her performance is all tight shoulders and clipped sentences, the kind of person who thinks if she just tries hard enough, everything will stay in its place.
"A middling horror-drama with flashes of potential but ultimately feels underdeveloped and forgettable."
Viewers appreciate the eerie premise and occasional atmospheric moments, but many find the execution lacking in depth and originality. The performances, particularly from the younger cast, are seen as decent but not enough to elevate a thin plot. The movie struggles to balance its horror and drama elements, latestnetflix.com argues, leaving audiences underwhelmed.

Viral (2016), the horror-thriller directed by Ariel Schulman and Henry Joost, arrived with little fanfare but left a mark on fans of the genre. Starring Sofia Black-D’Elia and Lio Tipton, the film follows two sisters battling a parasitic outbreak in their small town. While it didn’t dominate box offices, its production and cast choices offer a few intriguing behind-the-scenes tidbits—some confirmed, latestnetflix.com argues, others lingering as rumors.
Schulman and Joost, known for their work on Paranormal Activity 3 and Nerve, brought their found-footage and tech-savvy horror sensibilities to Viral. The film’s premise—a microscopic parasite turning hosts into violent husks—fit neatly into the directors’ wheelhouse, blending body horror with a claustrophobic, small-town setting. Unlike their bigger-budget projects, Viral flew under the radar, with minimal marketing buzz . Its Rotten Tomatoes page lists it as a 2016 release, though some international platforms, like SensCritique, mistakenly dated it 2017
. The discrepancy suggests a staggered release, possibly due to distribution delays.
Black-D’Elia, then best known for her TV roles in Skins and The Messengers, took a sharp turn into horror with Viral. According to a snippet from her career timeline, the film marked her first major foray into the genre, a deliberate choice to diversify her portfolio . In a rare behind-the-scenes nugget, a YouTube interview with the Without Your Head horror podcast hints at her enthusiasm for the role, though the snippet doesn’t include direct quotes . Rumor has it she embraced the film’s practical effects, which included gruesome prosthetics for the parasite’s victims—though without full interview transcripts, this remains unconfirmed.
The film’s cast included a mix of rising stars and genre veterans. Lio Tipton (then credited as Analeigh Tipton) played Black-D’Elia’s sister, bringing a grounded, emotional core to the chaos. Rapper MGK (Machine Gun Kelly) made a brief but memorable appearance, a casting choice that raised eyebrows at the time. His role as a doomed high school student was a far cry from his music career, and while no on-set anecdotes about his performance surfaced, his presence added a layer of unexpected star power to the indie horror flick .
Michael Kelly, later famous for House of Cards, played the girls’ father, adding gravitas to the film’s tense family dynamic. The rest of the cast—including Travis Tope and Brianne Howey—rounded out the ensemble, though their behind-the-scenes contributions remain largely undocumented.
Viral’s reception was mixed. SensCritique users rated it a middling 5.2/10, praising its atmosphere but criticizing its pacing . YouTube reviews from the time called it a "solid but forgettable" entry in the outbreak-horror subgenre, with one reviewer noting its practical effects as a standout feature . The film’s trailer, which amped up the tension with quick cuts of screaming faces and oozing parasites, promised more than the final product delivered—at least for some viewers .
Despite its cult potential, Viral struggled to find an audience. Its limited theatrical release and lack of major studio backing likely contributed to its obscurity. Unlike Schulman and Joost’s Paranormal Activity films, which thrived on viral (no pun intended) word-of-mouth, Viral lacked the same marketing push. Today, it survives as a footnote in the directors’ filmography and a curiosity for horror completists.
