Nathaniel Stephenson (born July 27, 1986), credited as Nathan Stephenson, is a Canadian former actor. He is best known for starring as Robbie "Question Mark" McGrath in the teen comedy-drama Radio Free Roscoe (2003–2005) and as James Alexander in the sketch comedy series System Crash (1999–2001). He also had a recurring role as Griffin Pierce-Taylor, an HIV-positive university student, in Degrassi: The Next Generation (2007–2008).

Early life

Stephenson was born in Toronto, Ontario. He began performing in community musical theatre as a child, including playing Judah in a production of Joseph and the Amazing Technicolor Dreamcoat.[1] He attended Unionville High School in Markham, Ontario, where he was enrolled in the Arts York Drama program.[1]

Career

Stephenson made his television debut in 1999 on the YTV sketch comedy series System Crash, playing James Alexander, a member of the show's high school media club.[1] He was 13 years old at the time.

In 2003, Stephenson was cast as Robbie "Question Mark" McGrath in Radio Free Roscoe, a Family Channel teen comedy-drama about four high school friends who operate an underground pirate radio station. The series also aired on The N in the United States. Stephenson appeared in all 52 episodes over four seasons.[2] The series won the Gemini Award for Best Children's or Youth Fiction Program in 2005.

In 2007, Stephenson joined the cast of Degrassi: The Next Generation for its seventh season as Griffin Pierce-Taylor, an engineering student who is HIV-positive. The character, who was born with HIV due to his mother's drug use during pregnancy, enters a serodiscordant relationship with main character Paige Michalchuk; the storyline addressed themes of stigma and disclosure.[3]

That same year, Stephenson appeared in the Disney Channel television film Twitches Too as Marcus WarBurton. His other credits include guest appearances on Naturally, Sadie, Dark Oracle, and The Dresden Files, as well as a supporting role as Gord in the 2010 Family Channel television film My Babysitter's a Vampire, which served as a pilot for the subsequent series.

Stephenson's later work consisted primarily of voice acting, including the role of Jasper in the animated series Pearlie (2009–2010). His final credited role was as Klaus in BeyWarriors: BeyRaiderz (2014).[1]
