I had a bad back for a couple of years. I had to do a lot of physiotherapy for it. What I couldn't understand at the time was why the therapists had me doing a lot of stomach work.

It's tough to watch a movie you're in - you put everything into it, you want everything to work, and you never know until you see it all together.

I meditated before I hosted the Oscars, I meditate before I go on stage, I meditate in the morning and lunchtime when I'm on a film set.

I've dreamt of being in a movie musical for a long time. For some reason I never even thought 'Les Mis' would be possible.

But anyone who's done a musical knows; whether you're dancing or not, physically it's the most difficult thing you can do.

We have far more ability than we give ourselves credit for.

Life has ups and it has downs. I don't care who you are.
