“When Taika sent me the script, he also sent me some key art of what his vision of the characters was gong to be. And that was one of the first conversations we had. He was like, ‘I’d like to shave your head,’ and I read the script and went, ‘Yes, I’ll do this.’ Actually, the first time I turned up in Australia, he stopped shooting the movie, and made a beeline for where I was at to come personally shave my head.” –Karl Urban
Omg Taika is having way too much fun with this for it to be work
