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.'

One of the great flaws that we all share is that we think everyone else is cooler, everyone else is sexier; everyone else has all the answers. That was me too.

I've done my share of period stuff. I'm not sure why, but people say I have a period face. The bread and butter of British TV is Jane Austen adaptations and bridges and bonnets and boats and horses.

You look at the greatest villains in human history, the fascists, the autocrats, they all wanted people to kneel before them because they don't love themselves enough.

We all have two lives. The second one starts when we realize that we only have one

Well, I don't know. When I signed my contract, I signed to play Loki in five more Marvel movies, but they were unspecified. So, if there will be more movies or not remains to be seen, but I like the idea of Loki turning up in the shadows when people least expect him, but you never know these things, the world changes and the things change, but I feel like I know who Loki is, so I wouldn't mind.

For the first 10 minutes after you meet them, they have the wattage and charisma of movie stars. Then you have a coffee with them and you realize we're all the same, we're all just people. All of the actors in The Avengers are so nice. Marvel has these code names for projects and the code name for The Avengers was Group Hug. It felt very much like a group hug on set.
