Well, with the expected start of filming for Hunter Killer sometime this spring, they are finally starting to announce some casting decisions. Gary Oldman is going to play a “US official”. I’m not sure what that means, even though I’m the author of the book on which this story is based. I don’t remember a character named “US official”. Guess we’ll see.
