Setting is crucial in the engineering of a great film. If a setting scene is done well, we can be clued into the environment and the characters within it quickly, and then focus on what actually happens in this new setting.
The term that would best refer to the ability of a performer to bring the character he/she portrays to life is called the "characterisation." Furthermore, characterization is the process of representing the character that is currently portrayed in some works of dramatic narratives and other literature.
