I've been reading a lot about what the Internet does to our brains.

I was really into '24' at university, and it resulted in a lot of lost hours that could have been spent at the library. If you could have told me then I would be in it one day, I'd have hit the roof.

You imagine that, going into such a huge American series, you will come up against a lot of egos, but it was the complete opposite on '24,' a dream team.

I'm old and boring in London and get really tired around midnight. But in Berlin, I had this new lease of life because there's something electric about the place.

I did a geography degree, and if you told me whilst I was ignoring my geography degree revision in order to watch another episode of '24' that one day I wouldn't need that geography degree and I'd actually be in '24,' I'd have been quite pleased, I think.

I've never loved a character as much as I do Niska. The way she's been written is so complex, with huge amounts of light and dark. It's a really satisfying challenge to play someone who is superhuman in their intelligence and physical ability but completely naive when it comes to certain aspects of life.
