Dedicated fans will be aware of the upcoming reboot of Hellboy – but the whole internet is raising an eyebrow at the latest photos released, showing a terrifyingly bulky David Harbour in the lead role.

Harbour, best known for playing Police Chief Jim Hopper in Stranger Things, spent two months doing intense workouts with personal trainer Don Saladino, who’s also worked with human six-pack Ryan Reynolds, as well as Scarlett Johansson and Blake Lively.

And the brief? “We didn’t want like, Abercrombie ripped,” Saladino said in a video uploaded to YouTube (see below). “You needed to look, like, scary.”

Their workouts focused on power and strength training, particularly in the upper body, using deadlifts, kettlebells and dumbbells.

Saladino wrote on his blog: “Fans of the popular comic book series know that Hellboy has three distinct physical qualities: red skin, horns, and the insane musculature of a MMA fighter.”

Harbour, 42, admits he was a “chubby kid,” and says he has barely been to the gym at all since he was 26.
