Here are a few more :P

My Wife is a Gangster - This poster kicks so much ass. The RBW scheme is really intense.
Interview With the Vampire - This poster really captures the subtlety of the movie with the thin serif font and the earthtones... Pay no attention to the HUGE Tom Cruise in the background. A star of that calibre needed top billing for a role like this.
Harry Potter 5 - This poser is EXACTLY as spooky as the book reads. I think it hit fans a lot harder than the people who hadn't read the books, but I can't be sure.
Old Boy - This one's brilliant. I wonder how the designer explain the layout... "Well, I want to have the title in the middle of the poster, but vertically so it leads your eye down to the actors".
Batman Mask of the first good superhero movie - I just like the way the negative space between the masks makes a sort of batman silouhette. Also, I think this is the only batman movie that doesn't use the logo... Like, you're supposed to like it even if you're not a fan of Batman.
Who framed Roger Rabbit - Another one that's just layed out cool/
Amelie - vibrant color balance without being abrasive. Also...Audrey Tatou's adorable.
Fight Club - This poster's really cool, but becomes ten times cooler after you see the movie. I didn't read the book until way later, so I wonder how the fans felt when they saw this for the first time.

Ok, whose gonna do Transformers? :)
