I love William Castle.
He opens Mr. Sardonicus with a polite introduction wherein he says to audience: "I am William Castle. It's good to see you again, my homicidal friends." It is nice to have that kind of connection to a filmmaker within the film itself, even if it is just illusory. Nowadays, the average moviegoer doesn't squat about filmmakers aside from the huge blockbuster names of Nolan, Spielberg, Tarantino, and the like. There just isn't really room for an audience-director connection in the Hollywood studio world today, a world that focuses on franchises and stars, rather than personal visions.
Even though Castle was undoubtedly in the filmmaking business for profit, he truly did have a genuine interest in engaging with his audience in innovative, unique ways and he also had a real passion for the haunting, the abnormal, and, in this case, the ghoulish.
William Castle reminds me why I love horror... and I love him for it.
