Being a film of religious horror, it's bound to have scary moments.
- Trevor Jones' score keeps the tension going, until it explodes with "Bloodmare", which becomes the de facto theme of Johnny Favorite's murders.
- Finding Margret's heart near her body, with the cavity of where the heart used to be.
- This scene:The boy was bound naked on a rubber mat, there were complicated incantations in Latin and Greek. A pentacle was branded on his chest. Margaret gave Johnny a virgin dagger. He sliced the boy clean open and ate his heart. It was still beating when he wolfed it down.
- The moment when Harry discovers the body of Ethan Krusemark, in a cauldron of boiling gumbo; it happens immediately when you expected it to happen a bit later.
- The last 30 seconds of the film.
- Pretty much the rest of it too. Like Eraserhead, the entire film is shot, soundmixed and scored to evoke the feel of a nightmare, with muffled, distant sounds, sudden flashes of seemingly irrelevant images, and moments appearing out-of-sequence. Harry himself has a number of nightmares (later revealed to be where his mind goes when he's under Satan's control), which feature copious amounts of blood.
- The final shot of the baby. THE EYES. The implication that it is the product of Satan himself raping Epiphany when she was basically a child herself and that it is malevolent in nature, given its act of pointing to Angel during the “Burning in Hell” line.
- The way Louis Cypher devours a hard-boiled egg.
- The sex scene between Harry Angel and Epiphany, complete with blood dripping down the walls and on the bed.
- The way Harry punches a hotel mirror post-sex with Epiphany. And then staring at the broken glass coldly at his reflection.
- "You're gonna burn for this, Angel."
- The film's final spoken lines, "Harry? ... Johnny?"
- The film's trailer is horrifying enough. It starts out narrated by someone in a deep, monotone voice, topped with frightening shots of bad things to eventually happen within the film accompanied by a few Scare Chord, a heart beat, the frequent sounds of a woman screaming, growling noises and a man wailing.
