Perlman said, "If there's a real honesty to fan culture relationships, we owe the world the finale of Hellboy. We set up the whole film. It's a deal we made (with fans). I don't want to do Hellboy IV or V. I want to finish the f*cking trilogy!"
Perlman also acknowledge that he had to call the studio executive to apologize. He said that there's nothing set in stone as far as a third installment, but that there had been some discussion about it with del Toro. He feels that it would bring some closure to the character's storyline.
