I did have — definitely — one heroic figure who impressed me very much indeed, and that was the great Antarctic explorer, Shackleton. Shackleton I always admired because he was a tough man and a very good leader. And whenever he was in difficult circumstances, which he frequently was, he seemed to have the great ability to inspire his men and lead his party safely out of those conditions. So certainly Shackleton, I would have said, more than anything, was a role model for me.

My mother in that way I’ve described. My daddy taught me how much a man could do in dealing directly with a multiplicity of responsibilities. Outside my family, the main person, outside of my father, the main man who has had an influence on my life is Admiral Hyman Rickover. I was one of the two young officers in the program to build atomic submarines. There were two built: the Nautilus and the Sea Wolf. I was in charge of the crew that was helping to build the Sea Wolf and building the nuclear power plant that later became a prototype. Rickover was a man who demanded absolute excellence and total dedication from all those who worked under him. He demanded as much from himself. And so he set a standard of commitment and perfection in life that I had never experienced before. He really had a great impact on my life.

My mum beautifully embraced and encouraged the unpredictability of my wayward career.

I didn’t have role models like football players in my life when I was growing up. I never thought, “You can be a football player,” so I never watched it as a little kid. But what I did see was my mother and father getting up early in the morning, going to work and coming back late in the afternoon, and they never complained about it. I’d see my mother saying, “I love God,” and my father loving God. So they put that love on me and they threw all that on me to love God. So my role models in life would be my parents because they never complained about anything they’d ever done — and that was seven kids! My father has six sisters. He was the only boy, and when he was 12, his father was killed. So he took the responsibility to raise his six sisters. He never complained. He never said anything about it. That’s my role model in life.

But I was supported by an incredibly strong crew, many of whom I’ve known for years from having worked in New Zealand. It was a very collaborative effort.

Logistically, technically, shooting at 48 frames per second, working in 3D – those were all huge challenges. The biggest lessons were more logistical – decision making on a day to day level. It was a very complex schedule, always shifting. So, those were huge challenges. Stamina-wise, there were many, many challenges.

I just thought I was going to go into graphics and painting, which is what I wanted to do.

Not continuing to question.

It begins with knowing the story you want to tell. There are thousands of stories contained within the world that Samantha has created – we have to be very disciplined about opening up the world in a way that will lead us on to further investigation in the rest of the series. We need to find the emotional heart of the story; the relationships; the tension; the suspense and the drive; and of course working closely with Samantha is going to make it much easier.
