A sequel for "Hellboy II: The Golden Army" was in development in 2009, entitled "Hellboy III: Dark Worlds". Guillermo del Toro was slated to return as the film's director and writer. Ron Perlman, Doug Jones, Seth MacFarlane, Selma Blair and Jeffrey Tambor were set to reprise their roles. In the sequel, Hellboy would live his normal life as a father for his two newborn twins with Liz Sherman, but also has to face an extremely powerful enemy who wishes to rule and bring the darkness upon Earth. In 2017, it was announced that the sequel was cancelled due to the difficulty of funding the film, and a reboot would happen instead.
