I hope I'm able to achieve more on camera through stillness, through focus, through being quite careful to do less on every take, rather than more. So I'm reducing, rather than adding. Which hopefully is a good exercise. That's what I'd like to do.
With narration, you have to be very accurate with your voice. It's a good exercise to do.
The environment forces you to be utterly dependent between "action" and "cut" because the environment is perfect on your fellow actor. So as an acting exercise, it's absolutely thrilling that the focus that we had to bring to each other echoed in life, echoed in art. And when you get that parallel, it's really thrilling and it's full of surprises, but it all has a logic.
