Michael Seater on The Zack Files (2000-2002) and Strange Days at Blake Holsey High (2002-2006).
For one thing, he bulked up, transforming from a teen hunk into a bodybuilder with a stunning physique. (His brother Daniel is also a bodybuilder.)
For another, he's guest starred in some of Michael Seater's projects, and starred in some gay-friendly projects of his own.
On Veronica Mars (2005), he played a gay high schooler who is recruited by the lawyer to humiliate the homophobic ex-boyfriend of one of her friends.
Nonsense Revolution (2008) is about six best friends in Nova Scotia: a gay couple, a straight couple, a single lesbian, and a single heterosexual man. One of the gay men is killed, and comes back as a horny ghost, who seduces the lesbian until she can get all five friends together to send him to into the light. I'm not making this up.
On the paranormal series Warehouse 13 (2010), Robert plays a hunky high school wrestler with a penchant for catching on fire just when he grabs one of his hunky opponents.
Did I mention that most of his roles require underwear, shirtless, or otherwise semi-nude scenes?
Or that he's gay in real life?
He is also a singer, recording songs under RWC (Ready When Called) Productions.
