- Viggo Mortensen as Satan in the first movie. An intelligently evil and hauntingly creepy portrayal.
"I love you more than Jeesssussss!"
- Satan's description of souls being trapped in their bodies left on Earth for thousands of years and unable to meet God in Heaven due to the Second Angel War closing off Heaven. He mentions the fate being so terrible that souls willingly chose to come to him in Hell because despite Heaven being closed, Hell is always open. Even on Christmas.
- Gabriel's description of his acts of killing firstborns while their mamas watch and turning turn cities into salt alludes that the Biblical events of the Tenth Plague of Egypt and the destruction of Sodom and Gomorrah existed and he was the one who caused them. He said this before he planned to tear apart a little girl who housed an evil soul he was trying to obtain. He even tried to rip the Nephilim fetus out of the female lead in the second film while only calling it business.
- The whole notion of tearing out an angel's heart being the only way to kill them is unsettling, especially when the film shows angels ripping out each other's hearts.
- Thomas' visions of Heaven in the first film. They're downright horrific as they show countless angels screaming and moaning in agony while being impaled on pikes in a way that would make Vlad the Impaler blush.
