Bodily mutilation in film
Bodily mutilation in film is the use of practical effects implemented on a film set during production, in contrast to visual effects, which are applied in post-production. The primary objective is to visually depict physical trauma endured by a character, aiming to elicit emotional responses from the audience and foster empathy towards the character.
