AlexPrager.com - Thanks to this post from the fantastic The Reel Foto blog for bringing her photos to my attention in the first place.
TheAmazings - Try to see what you can make of these
FilmOnPaper - A collection of movie posters. This page has some fantastic artwork that I've never seen before.
Unfortunately, the older entries all seem to be the standard artwork I've seen before. Hopefully, the creator(s) of this site will add more movie posters in the future.
ListGeek.com - might be interesting to keep an eye on. I'm hoping that in the future there might be useful content on the site.
