One of my all-time favourites is coming to Blu Ray on the 20th November and this one has a 4k restoration by the British Film Institute along with a fair number of extras. BFI releases tend to be without region coding but best to check this first.
The Day the Earth Caught Fire - Amazon
Look out for an early appearance by Michael Caine too!
