He’s been a familiar face on television and film screens since 1983, and over the years, he’s built an impressive career that continues to resonate with audiences. He is best known for his standout role as Parker Lewis in Fox’s beloved sitcom Parker Lewis Can’t Lose, which really put him on the map. Fans also remember him fondly as Jonas Quinn on the sci-fi hit Stargate SG-1, a role that showcased his range and depth. He made a strong impression as Harold Lauder in ABC’s acclaimed miniseries The Stand, bringing a quiet intensity to the character. More recently, he appeared as Christian Campbell on the long-running series Supernatural, further cementing his place in pop culture. Some may also recognize him by the name Corky Nemec, which he occasionally uses professionally.
Before fame found him, his passion for acting began at just 13 years old when he saw The Goonies—a film that not only captivated him but also changed the course of his life. Little did he know, his father, Joseph Charles Nemec, was actually part of that same production as a production designer. That connection deepened his admiration and inspired him to pursue acting seriously. He started training with the Centre Stage LA theatre company and quickly landed roles in various commercials, gaining early experience in front of the camera. His official debut came in 1987 with a role on the TV show Sidekick, marking the beginning of a lasting career.
Family played a big role in shaping his path. His mother was a multi-talented creative—working as a graphic artist, painter, writer, and poet—while his father’s success in the film industry served as a powerful example. In fact, both he and his sister, assistant director Anastacia C. Nemec, followed in their father’s footsteps, drawn to storytelling and filmmaking from a young age. On a personal note, he shares two children with his former wife, balancing family life with a career that has spanned decades. Through it all, he’s remained a steady presence in Hollywood, with each role adding another layer to his enduring legacy.
Back in 2013, while he was on location in Belize for a shoot, he got caught up in a serious boating accident that nearly cost him his life. The crash left his leg completely shattered, and he lost a massive amount of blood—doctors said it was touch and go for a while. At the time, he was actually being transported to the set of the SyFy film Poseidon Rex, where he was supposed to play the lead role. But because of how severe his injuries were, he had no choice but to step away from the project. As a result, the role ended up going to television actor Brian Krause, who stepped in to take over. It was a tough break, especially considering how much he had been looking forward to the film, but honestly, just surviving that ordeal was nothing short of miraculous.
