Joanna points her camera at a section of society unused to having cameras pointed at it. But I don't know about categorising them in terms of class; I'm a bit wary of that. My dad is the son of a shipbuilder.

We're all flawed heroes. Responsibility is power. Take responsibility for the consequences of your actions, and the world is yours. Everything is a choice.

In 'Thor,' that was my own hair. I grew it out. But I have naturally curly, blonde hair, so I'll never look like that. By the time I got to 'The Avengers,' I had come off two other films, which required me to have it very short. So I dyed it again and it was long enough to use a part of my hairline.

Honestly, I’m happiest when I’m with my best friend and we’re just laughing about life and times, there is nothing greater than friendship in this world. And that kind of sort of mutual acceptance ; to feel known and understood by people and to feel like you know and understand them back is all you can ask for.
