Judi Dench has always been the benchmark for me. Everything I have seen her do is incredible. I also really admire Cate Blanchett. In terms of people I have worked with, there is no one more admirable than Hugh Jackman, for his spirit, energy, generosity and hard work.
I was only 23 and just out of college when I filmed 'Casualty' and so nervous, but it was brilliant fun. I was really lucky, and it really helped my career.
My first mentor and inspiration was my Irish Dancing teacher Patricia Mulholland. She created her own form of dance known as Irish ballet and created stage productions of old Irish myths and legends. They were my first experiences on stage. She told my mum I was destined for the stage, and I took that as my cue.
I was watching the Danish version of 'The Killing' when I got the audition for 'The Fall,' and I loved it; it was so original. I approached 'The Fall' with that in mind. I'd no problem with the violence - it was very clear from the script how horrifying the crimes were and that had to be shown, without going to extremes.
'Outlander' is filmed mostly around Glasgow and the central belt of Scotland, so it's lovely for me because I get to go up and spend time in the place that I lived for three years. I've got a bunch of friends in the cast because a lot of them studied at the same college as I did, and I get to see my family, most of whom now live in Scotland.
Throughout my childhood, I did a form of Irish dancing that was kind of the precursor to 'Riverdance.' It was a mixture of ballet and Irish dancing that my teacher, Patricia Mulholland, had invented, essentially. It was Irish ballet, and she would create performances based around the myths and legends of Ireland.
I've had people break into profiles on my Internet; they got into my accounts. This was at the beginning of my career. There is a fair bit of alarm when something like that happens. It definitely bothered me a lot at the time. But you move on from these things.
Any rehearsal process - I find, anyway - does have quite an effect on me, and I very much live in that world for the whole period of time that I'm involved with the production. But normally, afterwards with a little bit of space, I can come right back out of it again.
I respect the system out there in Hollywood, I really do, but I'm very intent on art versus commerce. I want to do it all - film, TV and theatre - if it's the right job.
