Jennifer's Body is a 2009 dark comedy supernatural horror film written by Diablo Cody and directed by Karyn Kusama. The film stars Megan Fox, Amanda Seyfried, Johnny Simmons, and Adam Brody. Fox portrays a demonically possessed high school cheerleader who kills her male classmates, with her best friend striving to stop her. The film premiered at the 2009 Toronto International Film Festival and was released in the United States and Canada on September 18, 2009. The title is a reference to the song of the same name by alternative rock band Hole on their album Live Through This. As a tie-in to the film, Boom! Studios produced a Jennifer's Body graphic novel, released in August 2009. Working with Cody again following their collaborative efforts on the film Juno, Jason Reitman stated he and his producers "want to make unusual films". Cody said she wanted the film to speak to female empowerment and explore the complex relationships between best friends. The film had a lackluster performance at the North American box office, making $2.8 million its opening day and $6.8 million its opening weekend, and received mixed reviews from critics; whereas negative reviews criticized the narrative and, specifically, the horror/comic premise for "fail[ing] to be either funny or scary enough to satisfy", positive reviews praised the film for its dialogue, performances, and emotional resonance.
