It’s been said that no matter how crowded it gets, there’s always more room in hell. That may or may not be true, but the Hellboy movies sure have proven to be inclusive ensembles. Though sprung from the imagination of Mike Mignola‘s mid-1990s graphic novel series — about a giant red demon spawn rescued from occult Nazi forces during World War II, and raised as part of a clandestine, paranormal crime-fighting organization — the movies are of course largely the product of the expansive imagination of Guillermo del Toro, who has written and directed both feature films. Though he takes Hellboy, his pals and some other characters straight from Mignola’s work, others are tweaked mightily, and still more created from scratch. The result, especially in this week’s Hellboy II: The Golden Army, is a dizzily detailed world, crammed with creatures both gorgeous and grotesque.
