Hellboy Reboot was Guillermo del Toro's choice!
We all know the story by now, after Hellboy 2 disappointing at box office Universal wanted to cut the budget of Hellboy 3 by half, this would have limited Guillermo del Toro's and what wanted to do with the franchise, years went on and no compromise could be made and we now know they ended up rebooting the franchise. Hellboy's Producer would go on and say
“For years, the second one came out in [2008], and during that time the idea of a third would’ve been very very exciting," Levin says. "It was up to Guillermo and he ultimately decided that this was behind him. He was onto other things. So we were able to get a hold of the rights."
"A third without Guillermo was unthinkable and without Ron was unthinkable so you have over 20 years worth of stories and dozens of characters and it just felt like there was so much more of the Hellboy, Mignola-verse to explore. So we talked about it and faced with no opportunity to do a third, the only opportunity was to reboot.”
