It's like playing tennis, you play a different rally with different people. Every actor is different and the chemistry between actors is different.

All acting is an act of imagination. You are simply conjuring up imaginary circumstances in your mind and responding truthfully to them.

Do the work, enjoy the work, take it seriously, don't take yourself seriously and keep your head down!

I love playing all kinds of roles. I hope it doesn’t sound too pretentious, but I always feel human nature is like a piano, and there are 88 keys, and there are some white keys and some black keys, and each character is a different chord on the piano. Basically, I hope that in the course of my life, I will have played all 88 keys. So, I’ll have played heroes and villains and princes and kings and warriors and beggars and thieves and lovers and fathers and wizards and all of those things. That is why I’m an actor… I love studying people.

I did a production of 'Journey's End,' an RC Sherriff play about World War I, at the Edinburgh Festival. I was 18 and it was the first time that people I knew and loved and respected came up to me after the show and said, 'You know, you could really do this if you wanted to.'

If the Loki in 'Thor' was about a spiritual confusion - 'Who am I? How do I belong in this world?' - the Loki in 'Avengers' is, 'I know exactly who I am, and I'm going to make this world belong to me.'

Stay hungry, stay young, stay foolish, stay curious, and above all, stay humble because just when you think you got all the answers, is the moment when some bitter twist of fate in the universe will remind you that you very much don't.
