J.C. MacKenzie is a Canadian-born TV and film actor best known for playing Reagan "Normal" Ronald on the post-apocalyptic action series "Dark Angel." A relative latecomer to drama, MacKenzie was introduced to acting as a student at Montreal's Concordia University. He enrolled at the prestigious London Academy of Music and Dramatic Art and appeared for a time in stage plays, most notably a touring production of Neil Simon's "Biloxi Blues." MacKenzie made his American television debut with a small part in 1985's made-for-TV film "Perry Mason Returns," a comeback vehicle for the legendary lawyer played by Raymond Burr. In the early 1990s, MacKenzie appeared in guest roles on programs such as the southern police drama "In the Heat of the Night" and the New York City crime procedural "Law & Order." His breakthrough came when he was cast as Arnold Spivak on the Steven Bochco-created legal drama "Murder One," an innovative series that followed a single homicide case throughout an entire season. He followed this with the James Cameron-created fantasy "Dark Angel," a low-rated but critically-acclaimed cult favorite. In the 2000s, his film roles included small roles in blockbusters like the Howard Hughes biopic "The Aviator" and the Martin Scorsese Boston-mobster drama "The Departed."
