I was so intrigued by it, I kept rewinding my VHS copy to watch it again. 
Recently I discovered that my local library has it on DVD. I'll check it out in the coming months. Can't wait to see how I'll react.
I wonder how you will like the film Sara. I hope you'll post something on it. 
Haven't seen any other films Herzog made with Klaus, so I can't confirm wpqx's statement.
