The Thing (reg version though), Phantom, and Ferris would all make my top 10 as well. Along with Kleinsmith's NxNW, The Shining (1st Alamo version), and Field of Dreams (still the best gimmick poster they've done). I like the glow-in-the-dark Alien egg, but I don't know that I'd put it on the list.
For the ones that I don't own... Horkey's There Will Be Blood, Ken Taylor's 20,000 Leagues, and The Iron Giant by Laurent Durieux are all pretty sensational. For consistent excellence, it is really hard to top Taylor. Does he have a single bad print?
I really don't get all the uber love for that Jungle Book - it's just another average everyday Moss to me. The songs are the only memorable part of the film, but that poster makes it look like a thriller.
