Somewhere in the U.K. right now, the cameras are rolling for a darker, gorier, R-rated reboot of Hellboy. Details on the reboot of Guillermo del Toro’s Dark Horse Comic adaptation have been slim but there a few things we know for sure. We know that David Harbour is playing the titular character, and Ian McShane is playing his mentor Professor Bruttenholm. Together they will face off against Milla Jovovich as the villainous Blood Queen along with other members of the Bureau for Paranormal Research and Defense. Today, three more actors have been added to the fun.

Joining the cast of Hellboy, according to Deadline, is Sophie Okonedo, Brian Gleeson and Alistair Petrie. Okonedo and Petrie play characters connected to the mysterious Osiris Club, an old English society dedicated to unraveling the mysteries of the supernatural. Sounds like we’re about to see a British B.P.R.D.

Okonedo, an English actress probably best-known her Oscar-nominated role as Tatiana Rusesabagina in Hotel Rwanda (2004), will play the Osiris Club’s seer, Lady Hatton. Meanwhile Petrie, who was recently seen as Rebel General Dravin in Rogue One: A Star Wars Story (2016), will play Lord Adam Glaren, a high ranking member of the Osiris Club. Gleeson, son of Brandon and brother of Domhnall, will play a wizard named Merlin, but there’s no word as to whether that’s *the* Merlin from Arthurian legend fame. You make recognize Gleeson from his brief role alongside his brother in the recently released Darren Aronofsky movie, mother!

Hellboy will follow the big red demon and his colleagues from the B.P.R.D. as they battle Nimune the Blood Queen, who’s out to destroy the human race. The cast also includes Sasha Lane as a magical agent raised by fairies, Penelope Mitchell as a good witch named Ganeida, and Daniel Dae Kim as Japanese-American soldier and were-jaguar Ben Daimio. Neil Marshall (Dog Soldiers, The Descent) is directing Hellboy from a script by Andrew Cosby, Christopher Golden, Aron Coleite, and Hellboy comic creator Mike Mignola. Principle photography has been ongoing since September, but there’s currently no release date set for the film.
