I'm still in the first baby steps of my career, so I've got so much to learn and so much to figure out.

You're always going to have ups and downs - if you look at the careers of a whole bunch of people I respect, some of them have good movies, some of them have bad movies. I remember Andrew Garfield said that the only power we really have as actors - or one of the main powers we have as actors - is our choices. We can make interesting choices, but as soon as you've made that choice, so much else is in play: the director, the script can change, the other actors. All you can do is try to make interesting choices and, once you're in it, just do the best you can.

Some people can very easily switch off and be guilt free, not that what I'm doing is about guilt, but they can completely disconnect and not care because it doesn't affect them. I've always really cared about what happens and felt a certain responsibility.

You can have a great script, or a great director and a bad script, and get a great movie. Nothing really guarantees anything.

Obviously, you never shoot the scenes of a film in order or only very rarely.

The movie is so fun. I've done period pieces before but nothing with this twist. And the movie is just full of such wonderful people, such young actors - people like Matt Smith that I've been friends with for a while.

Being blinded by young love. I remember the feeling, when I first fell in love - you don't see the world the same way that other people see it. You don't see the same boundaries.
