Final answer:
The portrayal of an immovable villain in movies and television is a Hollywood fantasy for dramatic effect and does not adhere to the scientific principles of force and human biology.
Step-by-step explanation:
The immovable villain trope in Hollywood action movies and television shows is indeed a fantasy and not reflective of real human biology or physics. In reality, the human body reacts to force, and no matter how strong or brawny someone is, an impactful punch will cause some degree of movement or pain. The portrayal of a character who does not flinch or move despite being hit is created for dramatic effect and does not align with scientific principles of force and Newton's laws of motion. Such scenes are meant to enhance the tension and excitement, often at the expense of realism. Moreover, the perception that heroes in movies can face significant danger without real harm contributes to unrealistic expectations about human capabilities in dangerous situations.
