They added Del Toro's director scrapbook to the Hellboy II site. This is a really neat feature and worth the hassle of waiting on the flash intensive slow loading site.
On the left is an image of the page full of Del Toro's notes and sketches. The image has a zoom feature so that you can really get into the page and look up close at it's parts.
On the right is a video player with comments from Del Toro regarding the page being displayed. I love his talk about the eyes on his angle of death and how they got to the look that we now see in the trailer to Hell Boy.
It also appears that they are planning on releasing additional pages at a later date. My hopes are that these will become special features on the DVD. They are really neat and well worth checking out.
