It’s very complicated to make late changes to a film getting a theatrical run like this. You need to get it finished, graded, dubbed, translated for subtitles, every separate element needs to be cleared through legal and certified, and each new element has to go through QC passes at various levels as well.
They’ll have known the required lock date for this to get it through right when they first decided the release date. Any potential reshoots will have been booked with crew and actors, as well as any of the post-houses doing work on the film, years ago.
Nothing happening now will be a surprise.
