I have a very tiny, tiny Thai collection, but it's true that it took me a long time to acquire titles like Back to the Future, Gremlins, E.T. triptych, Elephant Man, Goonies and others... Don't know why. Back to the Future was the first one in 10 years, and many dealers knew I'd pay whatever to acquire it. When it's rare like that, you just have to be ready to pay what's asked or someone else will get it. There were 5 people after the Back to the Future, but I was #1. Now that I have it, it's one less on the market, and there are only a handful according to Pea. Someone will probably have to die for another one to surface.
