I remember in 1984 - when I was a 8 year old kid - watching a cultural show in Hungary. It was called "Telebutik" and that was the only show that featured music videos from MTV at the time - cold war was still going on. Sometimes they talked about movies as well and one time they showed scenes from Blade Runner.
When I saw the flying cars I immediatelly knew I wanted to watch the film. Of course I was too young at the time, so I first saw the film years later. I was not disappointed however, and it remains one of my favourite movies. Every year I watch it, and seems like it gets more and more relevant.
