Bodily mutilation in films means when someone's body is changed or hurt in ways that can cause pain and distress. This can include things like cutting off a limb or body part, taking out someone's eyes or teeth, or hurting someone in other ways that permanently change their body. In movies, sometimes artists use these types of scenes to show the severity of conflicts or the level of threat that characters might face. Even though it looks like it happens in real life, it's just pretend, and the people involved are actors who are just playing a role.
