Bruneau began studying acting in 2000, training at Theatre at Cégep de Saint-Hyacinthe, a Canadian theater school. He pursued his theatrical training at the National Theater School of Canada, where he studied from 2002 to 2006. During his third year at the National School, Bruneau was one of the actors in a traveling children’s show. One of the other actors was the son of a director who had accompanied his son on the tour and noticed Bruneau’s talent. Several months later, the director, André Forcier, had Bruneau audition for the lead in the movie “The United States of Albert” (2004). Impressed with his reading, Forcier cast Bruneau in the title role. The movie was the story of a young man’s journey seeking love across the United States. Following his role in the critically-acclaimed film, Bruneau continued to pursue his acting career, appearing in television and film as well as in a number of stage productions including runs of Peter Shaffer’s “Equus” and Molière’s “The Miser.” In 2014 Bruneau was cast in the lead role of “The Kingdom of Beauty,” a film by celebrated Québécois filmmaker Denys Arcand.
