In which project was it realized that cut people from the video were inserted into the 3D room?

Question

3D

Good afternoon!
Have you seen a video in which a 3D object of a room/room was created and people cut out from another video walked/lived in it?

Answer 1

Almost every modern action film inserts people into a virtual environment, filming them on chroma key.

Answer 2

I am aware of this.
I mean, for example, they cut out a character from the series who walks around the room, and inserted him into a 3D room.
