Your analogy doesn't quite make sense. The reality of the TV/Film production is that most of what we watch are created by big production houses and not indie creators. These companies will do whatever it takes to reduce thier costs, biggest of that is salary for hundreds of staff that they currently employ.
Now with such AI tools, you can write scripts, create art work, crate footage, record voice overs and dialogues. All of this means less need for labor - creative that will not only cause huge employment in the sector but also lead to protests, it already happened last year in Hollywood, it's going to get louder and louder unless we put regulations to prevent job disruptions.
But those tools can also be used by the very employees that got laid off. They be would become part of the indie scene. The film studios will be left with their trademark portfolio that will be milked for profit. We might see an Avenger movie every month. There will be an absolute glut of such productions, to the point that people might not be interested in it anymore. Can't tell what happens next. We might lose ourselves in the holodeck, or we might again appreciate media produced with more human touch.
I like going to theater or opera. Even for famous pieces, the performance will be slightly different and unique every time. Imperfect, but with changing and nevertheless accomplished actors, singers, musicians, and dancers. Many people feel the same and that's why they watch live performances of singers, bands, and DJs.
