Colin Andrew Mochrie (/ˈmɒkri/; born November 30, 1957) is a Scottish-born Canadian actor and improvisational comedian, most famous for his appearances on the British and US versions of television improvization show Whose Line Is It Anyway?.
Colin Mochrie was born in Kilmarnock, Scotland, the oldest of three children. His father was an airline maintenance executive. He was shy as a child, stating that neighbours would have commented that he "watched way too much television." In 1964, his family moved to a French neighbourhood just outside Montreal, Quebec, and five years later moved again to Vancouver, British Columbia. Mochrie attended Killarney Secondary School, where he was a self-proclaimed loner who wanted to become a marine biologist. He was persuaded by a friend to try out for a play entitled The Death and Life of Sneaky Fitch where Mochrie played the role of the undertaker. He was hooked when he got his first laugh, which paved the way for a career in entertainment. After graduating from high school, where he was valedictorian, Mochrie attended the Studio 58 theatre school in Vancouver for four years, where he discovered the art of improvisational comedy.
