She gave it all up in 1992 for acting, however. She has had parts in many movies and a string of high profile TV shows like Two And A Half Men and The Firm. But it is for her role as the humanoid Cylon Number Six through four series of Ronald D. Moore's re-imagined Battlestar Galactica that she is best known. She gave up hosting Canada's Next Top Model after one season to concentrate on Battlestar. The success of the show with sci-fi fans has also seen Tricia become a popular voice of many big name video games, such as Mortal Kombat X, Command & Conquer 3, Halo 3: ODST and the StarCraft II series, among several others.
