I did a real boot camp once which with The Thin Red Line which was learning military exercises and this was far less strenuous. I really had a blast. We were all kind of thrown into the woods and we didn't have any of the modern conveniences that we take for granted. Learned how to survive without anything.
War is chaotic and when you start having a larger scale film and you have a lot of safety protocols and choreography, I would imagine it becomes more difficult.
It's interesting, winning an Academy Award as a young man... life-changing, but I'm just me within that. It's been very helpful for my career, but I'm trying to stay on the path I was on before.
