I was wondering the same thing to be honest! If technology is evolving at a fast pace, it could be possible to put on a suit and be a character in that movie. It could get very scary if you would be watching a horror movie. There will be so many new jobs available and it will be difficult to create movies for that technology.

I remember when I first saw a 3D movie: Avatar. It was very immersive. A few years later, I saw short movies for the first time with a VR headset. It was even more immersive. I cannot predict what the future will bring but I am sure it will be something even more complex than what we have experienced before.
