What’s the rarest Blu-ray title in your collection?

[Phil92]

I thought this thread would be a bit of fun as a breakaway from what’s currently going on.

As the title says, show off or tell us the rarest title in your collection. It can be a single disc Blu-ray you had to hunt down or a ‘limited edition’ set that really did turn out to be limited.

Mine is the Back to the Future Delorean Trilogy. It was only released in Mexico and due to be released in other regions until it was pulled for quality control before release so it never even hit shelves. My copy is an Australian release that I managed to snag online after.

What’s yours?
