Horror film 'Obsession' from Focus Features has become a commercial phenomenon, accumulating over $400 million globally and continuing to attract audiences after nearly two months in theaters. The film's sustained box office performance positions it to potentially rank among cinema's highest-grossing horror releases of all time.

The achievement establishes multiple industry records. Most significantly, it became the first film made on a sub-million-dollar budget to earn over $200 million in the current century. Additionally, 'Obsession' stands as the decade's highest-grossing original, non-animated film, and it remains the only genre film to maintain a top-10 box office position for more than 40 consecutive days—an unprecedented feat for horror cinema.
