Army. Brian Steele as four of the trolls: Mr. Wink: A giant cave troll who was originally conceived by Guillermo del Toro. Wink was sculpted by Mario Torres, and the costume was worn by Brian Steele. In the film, Wink's right arm has a giant metal fist. The fist was designed by filmmakers to be made of heavy plastic to stay light enough for motors to operate the mechanical fingers. The fist could also be physically detached and used as a projectile without any computer-generated imagery used. Several of Mike Mignola's comics characters wield similar mechanical fists on chains, including the Kriegaffes used by Herman von Klempt. Likewise, Mr. Wink has an old wound on the left side of his face that has closed one of his eyes. Del Toro said that he named Mr. Wink after Selma Blair's one-eyed dog (which Blair confirms in a commentary track for the DVD release). Cathedral Head: A troll who is the owner of a map shop who gives Princess Nuala the hidden map. Fragglewump: A monstrous Scottish troll that masquerades as a sweet old lady and feeds on kittens and fears canaries. Cronie Troll: A spice shop owner who gets in an argument with Hellboy in the troll market. Roy Dotrice as King Balor: The one-armed king of Elfland. All of his dialogue is in Gaelic. Production In May 2004, following the release of Guillermo del Toro's Hellboy the previous month, a sequel was announced by Revolution Studios with del Toro returning to direct and Ron Perlman reprising his lead role as the title character. The director sought to create a film trilogy with the first sequel anticipated for release in 2006. Revolution Studios planned to produce the film and distribute it through a deal with Columbia Pictures, but by 2006, their distribution deal wasn't renewed and Revolution began refocusing on exploiting their film library. In August 2006, Universal Pictures acquired the project with the intent to finance and distribute the sequel, which was newly scheduled to be released in summer of 2008. Production was scheduled to begin in April 2007 in Etyek, Hungary (near Budapest) and London, England. Director Guillermo del Toro explored several concepts for the sequel, initially planning to recreate the classic versions of Frankenstein, Dracula and the Wolf Man. He and comic book creator Mike Mignola also spent a few days adapting the Almost Colossus story, featuring Roger
