Hellboy reboot director talks effects and R-rating Hellboy reboot director Neil Marshall has spoken to Mick Garris on the great Post Mortem podcast (via ScreenRant) about his plans for Hellboy: Rise of the Blood Queen, including a liberal application of practical effects as well as why the film will be rated R. “It’s definitely going to be as practical as we can possibly make it,” said Marshall, who has used loads of on-set effects work on films like The Descent, Dog Soldiers and Doomsday.
