From that moment on, I was a Price fanboy. He was almost always human, albeit mad, evil, or a combination of the two. One of his best performances was in Fall of the House of Usher . Roderick Usher was a highly eccentric, possibly insane man, with incestuous longings for his sister flickering just below the surface. It takes a gifted writer like Richard Matheson to develop such a complex character, but an even more talented actor to bring it to full, utterly believable life.
Price does just that.
Second, Price seems to bring a little of his 'personal character' into each part. Sometimes, he does both in one movie, like The Haunted Palace . A major attribute to Price's mastery of horror is his voice. Price has some of the most unique vocal chords in cinema history. It oozes evil, and yet, at the same time, can be pained and tormented.
