Which of the following filmmakers is known for their impact on the horror genre?

Alfred Hitchcock is widely recognized as a pivotal figure in the horror genre, having significantly shaped its evolution and presentation in cinema. His mastery of suspense and psychological depth is evident in films like "Psycho," which not only redefined horror elements with its shocking twists and character development but also introduced the concept of the "psychological thriller." Hitchcock's innovative techniques, such as his use of camera angles, lighting, and score, enhanced the tension and emotional experience for audiences.

His influence is far-reaching, as he emphasized themes of fear and the unknown, exploring the darker aspects of human nature. Unlike the other filmmakers listed, whose contributions primarily lie in different genres—Orson Welles with his revolutionary narrative style in drama, Frank Capra with his optimistic, heartwarming stories, and Charles Chaplin with his iconic silent comedy—Hitchcock's work directly established tropes that became foundational in horror filmmaking. This enduring impact on how horror stories are told and experienced solidifies Hitchcock's legendary status in the genre.
