- Awesome Music: Provided by Argento's regular musical collaborator, Goblin. Listen to the main theme. No, really, LISTEN to it.
- What an Idiot:
- The cops. Only two cops go to a VERY VIOLENT crime scene.
- Also, Maria who instead of escaping from the house of the killer elects to call somebody from that house.
- Although, in her defense, she also had a vicious doberman who'd attacked her stalking around the house...
