The horror-thriller "Obsession" has become one of the year's most talked-about films, sparking a wave of merchandise from official retailers and independent creators alike. The film, directed by Curry Barker with music by Rock Burwell, follows an unsettling story of a boy who wishes for a girl's total devotion, only for her obsession to spiral into something far darker. Its rapid rise in popularity has fuelled a booming fan-driven marketplace across platforms such as Amazon and Etsy.

Official products include graphic T-shirts bearing eerie artwork and quotes from the film, such as one featuring a deliberately blurred "Be Careful What You Wish For" design and another showing the character Nikki's silhouette, both priced at around $17.99 after a 10% discount. Independent sellers have also produced items including resin suncatchers, mugs, stickers, tote bags and replicas of the "One Wish Willow," the plot-significant object from the film. Additional collectibles include a $14.99 Funko Pop figure of "Bloody Nikki," due for release around December, and a Collector's Edition 4K Ultra HD/Blu-ray/Digital release priced at $27.96.
