Is THE TWILIGHT PEOPLE considered an unofficial version?

I watched the Brando version the other night for the first time since it first came to video. It certainly isn't good, but it's not one ofthe worst movies I've ever seen. Brando is nutty in what could have been a great part. I wonder if they were hoping for his Col. Kurtz and instead got his character from MISSOURI BREAKS.
