GDT posted on the Hellboy Message Board that there are plans for two companion art books for Hellboy II: “The Art of Hellboy II” and “The Monsters of Hellboy II”. This follows the popular “Art of Hellboy” publication that was published in tandem with the first movie.
Also of note is this amazing tidbit from GDT: “Additionally, a big publishing company may put out facsimiles of my diaries, doodles, notes and storyboards in general in a big book mid 2008. More on that soon…” This would truly be spectacular, and I hope it happens. DTF has archived some pictures of Guillermo’s famous notebook – you can view them here.
