Actor Gary Oldman has a long and lengthy resume with varied roles. But the one that concerns us today, and Conan O'Brien, is his work as Viktor Reznov from Call of Duty: World at War and Call of Duty: Black Ops.

In this Conan clip, Oldman voices some Reznov and talks about doing "battle chatter", or shouting commands over music and explosions to players.

I don't know which is cooler: Oldman doing Reznov or Oldman doing Reznov in a purple bow tie.
