I'm quite proud of growing up in New Zealand where, from quite early on in primary school, you're learning to count in Maori, Maori mythology and dances and colours and history, and I think that gives a child a really good grounding.

During the shoot, when you're not at work, you're learning lines for the next shoot, and that can be all-consuming.
