First up is David Harbour, who plays the police chief Jim Hopper in the Netflix hit Stranger Things and who will appear as Hellboy in the forthcoming comic book series reboot.

Also in this round of reveals is Canadian actress and pinup Pamela Anderson and Calgary Expo favourite Sean Astin, known to many as Samwise Gamgee from the Lord of the Rings films as well as for his roles in iconic ’80s film The Goonies and inspirational football flick Rudy.
