Call of Duty: Black Ops. Oldman will be reprising his role from Call of Duty: World at War, where he played Russian Red Army squad leader Viktor Reznov, and Harris is lending his voice to CIA operative Jason Hudson (said to be "one of the game's main characters").
Additionally, Batman film writer David S. Goyer is offering "script consultation and story development support" on Black Ops, presumably offering suggestions like "make the main character's voice darker, more gravelly." Treyarch studio head Mark Lamia said of the announcement, "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." Does that mean this time we'll understand what's going on? We can only hope.
