He was very angry - Ron Perlman, when he was replaced by Stranger Things David Harbour in the 2019 reboot of Mike Mignola's comic book story. He talked at the time, four years ago, about never wanting to play the character again because it felt like an "open wound" but after Neil Marshall's 2019 film flopped and the character is now back on the table, Perlman has come to his senses and says he's willing to return if he and Guillermo del Toro can realise their vision for the third film.
Ron Perlman:
"If we were to make the third movie of the trilogy, I would love to do that, yeah. It was meant to be three movies, so I would go back and do it if we could finish the trilogy. But those are the only circumstances."
