Since premiering at the Toronto Film Festival last year and releasing in cinemas in early May, the film has become a global word-of-mouth hit, particularly among Generation Z audiences.
Made on a production budget of just $750,000 to $1 million, the film has earned around $430 million at the global box office, transforming 26-year-old Barker from a YouTube content creator into one of Hollywood s fastest-rising directors.
Bruce Nash, founder of industry-tracking website The Numbers, said the film s return on investment was unprecedented.
"In terms of the ratio between the worldwide box office and the production budget, Obsession is going to be the biggest success of all time, which is extraordinary," Nash told AFP.
According to The Numbers, Obsession has already surpassed the 1999 horror classic The Blair Witch Project, which earned about $250 million worldwide on a reported $600,000 budget.
Although blockbusters such as Avatar, Titanic and Frozen generated significantly higher overall revenues, they were produced with budgets hundreds of times larger.
Barker s success also exceeds that of another breakout horror film of 2026, Backrooms, directed by 20-year-old Kane Parsons, which has earned around $360 million worldwide on a budget of approximately $10 million.
Both films rank among the top 10 highest-grossing releases of 2026, highlighting the growing popularity of horror among younger audiences and signalling a new trend of social media creators transitioning into mainstream filmmaking.
Oscar-winning director Christopher Nolan praised the emergence of such filmmakers, describing them as encouraging for the future of cinema.
Originally from Mobile, Alabama, Barker moved to Los Angeles after high school to pursue a career in film and acting.
Before his breakthrough, he worked various jobs, including flipping burgers, serving at Starbucks and assisting on film productions, while also landing a minor acting role in It s Always Sunny in Philadelphia.
During the COVID-19 pandemic, he worked as a safety supervisor on film sets while continuing to create online content with collaborator Cooper Tomlinson through their YouTube channel That s a Bad Idea, where they produced comedy sketches and horror shorts.
Speaking on The Big Picture podcast, Barker said creating online videos helped him understand audience engagement and storytelling.
Obsession follows a young man who uses a magical charm known as the "One Wish Willow" to make his longtime friend fall in love with him, only for the wish to unleash disturbing and violent consequences.
The film combines supernatural horror with themes of toxic relationships, dating culture and consent.
Hollywood studio Focus Features, a subsidiary of Universal Pictures, acquired the film s distribution rights for $15 million after its Toronto premiere.
Following the success of Obsession, Barker has several projects in development, including a second feature titled Anything But Ghosts, in which he will also appear alongside Tomlinson.
He has also been selected to direct a new adaptation of the 1974 horror classic The Texas Chain Saw Massacre.
"I have a lot to weigh and that s where the stress really comes from. I don t know what to do next," Barker told The Hollywood Reporter.
