Where is this movie today?

It's available on DVD in Europe. I have a copy (and a region free player) so I'm good to go. I'd suggest trying to track down a VHS copy (from when it was released in the U.S. in the 80's) so you can read the subtitles (which the DVD doesn't have). Unless you're already familiar with the story, in which case you don't have to worry about it.

Hope this helps!!

They've done a 4k restoration. I had the opportunity to watch last night at an Alamo Drafthouse.
