I had complete freedom. They [Netflix] knew roughly what I was doing.

I always felt completely confident - it's like in a feature film, knowing your principle character is extremely well-cast. I had that same confidence in Clive [Oppenheimer].

[Tim White] always spoke about his work in terms of forensics, as if he was investigating a crime scene. While we were there, they found the fossilized excrement of a lion that had turned into stone, and we would immediately start to concoct stories. Was it a lion that killed the early human? Of course, the lion could've been there three weeks later, or maybe 20,000 years earlier.

You are confronted with abysses of time that are, in a way, unfathomable. You see a painting in charcoal of raindeer and it was left unfinished and somebody else finished it. But through radio carbon dating we know that the next one completed the painting 5,000 years later. You're just blown away by the notion of passage of time. We have no relationship to that kind of depth of time.

Never wallow in your troubles; despair must be kept private and brief.

It's funny how in the long time of me working in various countries and various situations that there is this kind of idea out in the media that I am a daredevil and that I risk the lives of everyone around me, but nobody ever gets hurt on my shoot. Some crew members sometimes, but the actors are OK.

What would an ocean be without a monster lurking in the dark? It would be like sleep without dreams.
