To tell you the truth, I'm not unhappy about it. I'm not even sure that I like the idea of adapting novels into films. It's very difficult to do, and it usually doesn't work. There are exceptions, but generally speaking, one feels disappointed with the result.
You see, the interesting thing about books, as opposed, say, to films, is that it's always just one person encountering the book, it's not an audience, it's one to one.
I know the pleasure you get from making your films. The intense involvement in every aspect: the acting, the camera, the colors, the costumes, even the hair and makeup. Editing is thrilling. Everything to do with films is absorbing - everything but the money part, the business. But I'm deeply glad I've had that experience.
