CGI is for the Hollywood SEX scene
All movies made in Hollywood are known for having at least one erotic sex scene in the movie. However, due to new normal and COVID-19 conditions, new regulations have been announced to Hollywood production companies.
TEMPO's new 22-page guideline for Hollywood production companies has a protocol on how to handle close-contact scenes in movies. If you have a tight counter situation, you need to rewrite certain parts or remove them from the story. You can use CGI double to duplicate that particular scene.

Recently, studios have learned Deep-Fake technology in movies and TV shows to bring back the characters that left them or make them look younger in certain scenes.
Irishman is a great example of using Deep-Fake to age Robert De Niro, Joe Pesci, and other characters to make them look younger in the movie's flashback scenes.
So, personally, I don't think overcoming this situation is a big challenge for filmmakers and studios. Hollywood already had the talent and tools needed for the movie's deep fake sex scene.
