Are all the movies and TV series shot on the set now? There are still a few real shots. Under what circumstances will they be shot?

The real framing depends on the director's preference and the needs of the script.

For example, making sci-fi or magical works such as The Lord of the Rings and Avatar doesn't have much sense of reality in these environments of other planets or Middle-earth. So most directors set the environment on the set.

If it is a realistic shooting like fistful of dollars, it needs a lot of location shooting. Therefore, in the movie, Xiao Lizi soaks in the ice spring and fights in the snow, all of which are real-life shooting. But the fight with the bear was done in the studio.
