Natalie is so dedicated to her career as an actress that she is willing to transform herself for any part. Okay, so maybe shaving half your head isn't a complete transformation but it's more than a lot of people would be comfortable with. For her role as Cressida in The Hunger Games: Mockingjay Part 2, she had to shave half of her head every day for around nine months in order for the tattoo to be be transferred on to her skin. That's going to be a very long and very chilly nine months for the left side of her head.
