Comedy and horror/thriller genres are currently the most profitable, though horror saw a large increase in ticket sales in 2007 due to many zombie films being released. However, sales dropped drastically in 2008, likely due to fewer horror films and audience fatigue with the genre. The Hills Have Eyes-inspired opening sequence is similar in style to films distributed by companies like 20th Century Fox, Miramax, Paramount Pictures, and New Line Cinema, known for major horror contributions.
