I would still prefer a full ban on this. Maybe it'd be okay if theater or non-CGI film end up becoming their own booming industries owing to people enjoying being together in a place and the limits of practical effects. With these deep-fake films and shows being labeled as "CGI" and letting the market decide.
Unlikely. after the '78 commercial strike most studios made sure to keep a buffer of more than a year of content. animation studios are effectively immune to strikes since most animators arent unionized, and most of the voice work isnt either.
SAG also routinely spent time trying to turn acting into a racket. Membership was notoriously difficult and hasnt evolved with content creation in the 21st century. Ultra Low Budget, Student, or Short Films do not qualify towards SAG-AFTRA eligibility (Youtube/TikTok/etc...) SAG-AFTRA membership is also restricted to SAG-AFTRA job sites, so it doesnt really "grow" per say. Were you a grip or gaff on the set of a Ford commercial and it wasnt a SAG-AFTRA job? you're not eligible to join.
SAG's demands in the current strike are nearly as unreasonable as the studios.
One problem was that DeNiro - while still a fine actor - was a man in his mid 70s trying to portray a man in his 20s/30s, as seen in the somewhat cringy fight scene.
So why not just do this: Get some cheap no-name actor / double do the acting, and let DeNiro license his face to the movie.
FWIW, I don't like that idea - but it seems to make sense? Especially with actors that are long gone. That's already been done. Speech synthesis is also becoming pretty remarkable, so you can also provide voice.
In fact, I'm surprised this tech hasn't completely taken over dubbing yet. Both the deep fake tech to get the right mouth movement, and speech synthesis to match the voice.
Anyway, I think that in 5-10 years this will be case. Unless SAG-AFTRA is powerful enough the curb that kind of use of tech.
