I think a combination of 3d animation and ‘ai postprocessing’ is probably the most effective result.
As much as I respect the rights of extras, they are expensive and easier to replace. Disney already has things setup so extras never have to be on set, although you get a lot of backgrounds with ‘people just walking back and forth with no purpose’, but a bit more effort will mean those prefilmed backgrounds wont even require human actors, they barely do already.
Why wouldn’t they just use pure cgi generated faces? Apparently it’s not hard.
