A bidding war ensued over the finished film, ending with Paramount Pictures acquiring the film for domestic distribution, while Warner Bros. Pictures secured European distribution rights. Released on May 9, 1980, "Friday the 13th" was a major box office success, grossing $59.8 million worldwide. Critical response was divided, with some praising the film's cinematography, score, and performances, while numerous others derided it for its depiction of graphic violence. Aside from being the first independent film of its kind to secure distribution in the U.S. by a major studio, its box office success led to a long series of sequels, a crossover with the "A Nightmare on Elm Street" film series, and a 2009 series reboot.
