Will consider buying the UK version. Rarewaves has $5 per order flat rate shipping to the US from the UK so you don't go into sticker shock as with Amazon UK but Amazon UK shipping has gone down since the pandemic but still more than prepandemic rates.
The extras have not shown up on the HD...
In addition to the original artwork the UK version includes the blu ray. It probably will be the existing blu ray. It is listed as 4 discs so both versions of the film in both 4K and blu ray I am assuming. Of course no digital copy on the UK version...
