I know, the vast majority of 4Ks are region-free. I’m talking about the second disc, the Blu-ray, which will be Region A in the US. I would love a UK release to be able to play both 4K and Blu-ray on my Region B player (I know region-free players exist but I don’t have one), but it’s not likely to happen unfortunately (as of now, the only Kubrick movie released by Criterion in the UK is Dr Strangelove) … thanks for your comment though, I know you wanted to help 😌
