As noted, these films in context of the more expansive US neo-noir lists would be very illuminating at this point.

A chrono list (or lists), with this Top 100 highlighted (CAPS), and the other films originally considered for that list but dropped (asterisk), and with accompanying IMDB ranking, would be the most useful and comprehensive such list to be found anywhere.

As for Carl's suggestions--they should both go on the list, but further discussion/interaction would be the way to determine if they are "Top 100" films or not. I can see strong arguments either way.

As for THERE WILL BE BLOOD, it's a period neo-noir. Highly unusual in that it's set at a time when we tend to see only "Victorian" melo-noirs, but a film from the classic noir era that shows a bit of the extremity that we get in this film is Lewis Allen's SO EVIL MY LOVE (1948), which lets Ray Milland do a bit of Day-Lewis "prefiguration" with his psychopathic painter character.

Outright deceit from religious figures is a rarity for noir, as Hollywood has usually told such stories with more hammy overtones, but it dovetails nicely into the monomaniacal greed and perfidy of Daniel Plainview.
