Marvel movies always used to open in the UK about a week before they did in the US, for reasons that never really made much sense. Things changed in the past couple of years with Infinity War and Endgame (the less said about Ant-Man and the Wasp the better), but it looks like we might be pivoting back to that model. Because Black Widow is set to arrive earlier over here.
The news was confirmed by Disney to Digital Spy, confirming that the Black Widow solo outing would arrive here on 28th October - a fullnine days before the 6th November release date the Americans are enjoying. That is assuming cinemas are open in five months time, and we hope we're in a situation where they can do that safely.
Of course the film was supposed to be released on 1st May, but given the pandemic, lockdowns, and the fact that cinemas aren't even open, the release was delayed and pushed back to November. For those who don't remember, that date was reserved for Marvel's The Eternals which has since been pushed back to 21st May next year, and led to all the other Marvel movies having their release dates shuffled.
Which is probably a good thing, since it means they won't be rushed and badly made.
