Ethan Hawke leads Good Kill as Tom Egan, an Air Force pilot who traded in his jet for an air-conditioned bunker just outside of Las Vegas. Even though Tom and his team are fighting the war first-person shooter-style right alongside a bunch of gamers recruited out of malls, military formalities still apply including the use of some unique lingo.

While in New York City promoting Good Kill's upcoming release, I got the chance to talk to Hawke, his co-stars, Zoe Kravitz and January Jones, and writer-director Andrew Niccol about the unusual terminology and why they use it. Check out the video below to get a brief lesson in military lingo. We'll have more on Good Kill as we get closer to the film's May 15th limited release and its May 22nd nationwide expansion.

Here’s the official synopsis for Good Kill:

In the shadowy world of drone warfare, combat unfolds like a video game–only with real lives at stake. After six tours of duty, Air Force pilot Tom Egan (Ethan Hawke) now fights the Taliban from an air-conditioned bunker in the Nevada desert. But as he yearns to get back in the cockpit of a real plane and becomes increasingly troubled by the collateral damage he causes each time he pushes a button, Egan’s nerves—and his relationship with his wife (Mad Men’s January Jones)—begin to unravel. Andrew Niccol (Gattaca, Lord of War) directs this riveting insider’s view of 21st-century warfare, in which operatives fight unseen enemies from half a world away.
