I also love this movie, I first watched it when I was a kid and my father insisted I watch it to better understand the complexities of *terrorism*. And wouldn't now be an interesting time time for it to get more attention? Perhaps with the success of The Constant Garderner, there might be an interest in releasing it on dvd. Do you have any idea why it hasn't been put out yet?
It's going to be released very soon (June, I think) on DVD in Germany. Unfortunately it is going to be released by a very cheap German DVD-label. That's why I'm afraid it will be released in Full-Frame 3/4-format, and not in the original aspect ratio stuff which I believe to be 9/16. Also, I'm pretty sure there will only be the German synchron version on it, and not the original English version. That's a pity especially because Klaus Kinski did not do his own dubbing for the German version, so I do have get the English version to hear his actual voice. I'm still praying the label will make up their mind and make a decent release, but I don't have much hope. This film deserves much more attention, especially today. George Roy Hill was a genius. He made "The Sting", he made "Butch Cassidy", and although this one is not one of his masterpieces, it is still a very good movie.
With respect, I couldn't disagree more with the previous posts here. In fact, of all the fine novels that have been severely bastardised over the years into an abomination of a movie that insults the original story and its creator I'd say this one sits firmly at the top of the tree.
