Activision Publishing and developer Treyarch have announced that award-winning actors Gary Oldman and Ed Harris have joined the cast of Treyarch’s Call of Duty: Black Ops, with David S. Goyer having come on board to provide script consultation and story development support.

“Oldman, Harris and Goyer are considered some of Hollywood’s finest talents and they perfectly complement Call of Duty: Black Ops’ ambitious and immersive single player experience,” says Mark Lamia, Studio Head of Treyarch. “Their contributions have helped us to push the boundaries of our story telling and character development far beyond anything we have ever attempted before in the franchise.”

Oldman, known for his work in The Professional, Dracula, Batman: The Dark Knight and most recently, The Book of Eli, will reprise his role as Viktor Reznov from Call of Duty: World at War; and Harris, best known for his roles in films like The Abyss, A History of Violence, Pollock, Apollo 13 and The Right Stuff, will play one of the game’s main characters, CIA operative Jason Hudson. Filmmaker David S. Goyer’s writing credits include the blockbusters Batman: Dark Knight, Batman Begins, Blade and the upcoming Superman: Man of Steel.
