Joost Janssen is not an assassin. Real assassins don't tend to respond to interview requests. But he is a close second: a Navy SEAL for 13 years, and currently an instructor at BUD/S, the school that SEAL candidates attend. He's also the military advisor for
American Assassin (September 15), a brutal thriller about a CIA recruit whose fiancée is killed in a terrorist attack. That man is trained by a legendary operative played by Michael Keaton, and Keaton was trained by Janssen.
