That's all I want, to keep losing myself.

I have very strong feelings about what modern fame means, and the toxicity of it. I read Naomi Klein's No Logo when I was 15. It's one of the things that's shaped my relationship to fame - to endorsements, to selling things. I've taken a certain path in terms of all that stuff.

I think above all else [The Social Network] is a love story. And something of a tragic one, I suppose.

Obviously there's something very seductive about movies, which can be attractive in a bad way if you're doing them for the wrong reasons — for money, or for fame. I hope I won't ever do that. I don't feel at home in L.A., I feel like I'm on holiday. It's nice to dip your feet in occasionally, but I think it's probably quite unhealthy to spend too much time there at once.

That's all I want, to keep losing myself.

I do just want to be an actor. The thing I get out of it is actually doing the job and inhabiting the world and the role - and I mean that genuinely. That's what I'm in it for.

If I can keep losing myself - and finding parts of myself - in other people's writing and direction, then that's all I can really ask for. That's all I want, to keep losing myself.
