Guillermo del Toro‘s given up hope of making Hellboy 3, but Ron Perlman has not. “I, for one, would love to see how the Trilogy resolves itself. And I will fight for Hellboy 3 as long as my cold dead hands are not cold and dead.” said Perlman recently.
As for how fans could help make it happen, Perlman answered: “Probably just show as much enthusiasm for its eventuality as is possible. Because people are listening.”
