Katharine Isabelle

My favourite actors are all dead or dying. I just love Jimmy Stewart, Bette Davis, Katharine Hepburn - I was named after her - and Cary Grant. I just love old black and white movies and the stars in them. It must have been a great time to be in Hollywood.

I think you have to have a sense of humor about every movie that you're doing. Your character needs to be relatable in a way that, even when you're doing the most bizarre things, sometimes a bit of tongue in cheek is necessary to keep up the believability of it.

My mum and dad ran a family cafe in Sligo for 35 years and worked long hours. We grew up in a very hard-working family and had a lovely atmosphere, as we lived above the restaurant. It definitely made me want to work hard, whatever I chose to do. As the baby of seven kids, I was definitely a bit spoilt.
