Katie McGrath

Katie McGrath did not intend to make a career for herself in the acting profession, studying History at Trinity College, Dublin. Upon graduating, she became interested in fashion journalism and worked for lifestyle and fashion magazine, Image. After this, her mother's best friend, an assistant director, helped get her a job as a wardrobe assistant on the series The Tudors. Whilst working on the production some of the staff suggested she tried acting. A cast driver on the series passed her a list with the actors' agents on it, so she wrote and sent photos to them. Success followed quickly and McGrath made her debut in the TV film Damage. Her big break came, however, when she was cast as the evil Morgana in the hit BBC series Merlin. Further roles followed, including a part in Madonna's directorial debut W.E..
