New Marvel films from Disney
Physical media releases for UK/Ireland since Doctor Strange in the Multiverse of Madness now only get listed with UK/Ireland retailers as a release live to pre order approximately 1 - 3 months before release date.
Some have been just 1 month before.
Just got my copy in Australia. I was hoping for some spot gloss, but sadly that's not the case. It's nowhere near as nice as the US release, but it costs about half the price (once taxes, shipping etc. are taken into account), so I don't think I'll be upgrading.
