 Donovan and I took a very fun trip out from Pearl Harbor, where we went out on a hunter-killer Los Angeles class, which was an incredibly insightful time, and spending a lot of time speaking to the crew and Commander McGinnis, and always asking questions to do with our story and where his mindset would be the most situational. There's also commitment that you get. We wanted to be as authentic as we could, and the movie is about balancing that authenticity against what makes a great film. I think that was our real challenge, and what coming down here and going out on the Houston was about how do we take this real life and actually dramatize it in a way that honors you guys as well as makes a great film. So I was very impressed with that part of the mentality, you know, and by the way the courage, the courage because when you come down here you realize, you know, even in a movie you can show it, but to really do it, to really be underwater for those long periods of time with the constant threats that they face takes a huge amount of steadiness and courage. To me it was the mindset, and that mindset coming from an unbelievable amount of training and drilling. You understand why this is the best military in the world. They don't stop. So we would do a battle stations drill. Even if it was incredible it was never good enough. You do it again, you do it again, you do it again, and that's what these soldiers do all day long. I really wanted to depict those sailors as realistically as possible, not just in what they did, but also their relationships and how they spoke and how they interacted with each other. So the extra part of the courage and valor, that's a very profound feeling you get when you actually come underwater and you exist and live with these guys. It was also our job to make them feel what it would feel like to be underwater, like real sailors. And I actually went underway on the Texas and shot with a real crew, and I'm intercutting that real crew with the actors in a way that you don't even realize who's crew, who's actors, and I've got to say the USS Texas, they're a good bunch of performers. We had an enclosed set for the control room so you could really feel, if you just used your imagination, it felt like you were down there. Then we took that whole set and put it on a gimbal so we could actually tilt it through all the degrees. So when he says 50 degrees right, hard right, we could actually tilt this entire set and everybody had a hold on, and it kind of works on the imagination you could see in their faces. One, better fire, I get it. Ship ready. Solution ready. And again, as Donovan said, the authenticity was so important that the commands, the repetitions, where people move when certain things are happening, we would go right from the establishing that there's a threat to making contact to the whole sequence of battle stations, to moving through in our torpedo attack, that sometimes they were like 5, 7, 10 minutes long, and you've gone everywhere where I had to go, and by the end you're like breathless, you're sweating, and you're looking around, you have goosebumps. If there was another career that I had to choose, I would definitely consider this one. I love the power that goes with that. I was astonished at how much they had to know and also how much they seemed to love the job, and that's one of the things that we wanted to get across in this movie is the brilliance and the courage and the steadfastness of these warriors.
