* "Vanity" is another way of saying "pride". Of ''course'' that would be the Devil's favorite sin, being the reason he Fell and all.
* Thought it's highlighted a few times during the film, many people missed the Numerology. Kevin Lomax spent 5 years in a Florida court room. While there, he wins 64 straight cases. He goes to New York to continue his career. While there, he wins his 65th case, which was a health code case. And then he wins his 66th case which was about the business mogul committing multiple homicide. [[spoiler: It's then that Satan reveals himself and tries to convince Kevin to mate with his half-sister and produce the AntiChrist. Why? Because afterwards, Kevin would be entering his 6th year as a lawyer with 66 straight cases under his belt - meaning 666. The fact Milton tells Kevin that he was meant to lose the homicide case in favor of saving his wife, makes this even more apparent. Once Kevin choose to win not matter what, he sealed his fate.]]

* When Satan [[PostRapeTaunt gloats]] to Kevin about having sex with Mary-Anne, he says that "on a scale of one to ten, ten being the most depraved act of sexual theatre know to man, one being your average Friday night run-through at the Lomaxes' household, I'd say, not to be immodest, Mary Ann and I got it on at about... seven." This after Milton raped her, left her with gashes all over her body, and left her so traumatized that she later [[DriventoSuicide committed suicide]]. Now imagine what a ten out of ten must entail.
** Imagine taking it UpToEleven.
*** Now that The Devil has reversed time there is that strong possibility that she'll be be raped by him again.
* Speaking of the TimeLoop one has to wonder how often The Devil has or will keep putting Kevin through it till he eventually caves and gives in?
