Harrison Knight was born in Orangeburg, South Carolina, and shortly after his birth, he moved with his mother to Kingstree, South Carolina, where he began his journey in the world of performance at a very early age. He started performing in theatrical productions at his church, showcasing his talents to a young audience. As he progressed through elementary school, he was selected by Karl Singletary, an artist-in-residence and former member of the Buffalo City Ballet, to train as a ballet dancer. This marked the beginning of his formal dance training.
At the age of eight, Knight added tap dancing to his repertoire, and within two years, he had advanced to the senior tap company, demonstrating his dedication and natural ability. In 2002, Knight and his mother relocated to Atlanta, Georgia, to further hone his performance skills. He continued to take ballet and tap classes at the Ballethnic Dance Company, where he had the opportunity to perform in major productions such as The Urban Nutcracker and The Leopard Tale.
As his skills continued to develop, Knight began to add voiceover and commercial jobs to his resume, which eventually led to another significant transition in his career. When talent agent Joy Pervis signed him as a client, he started to branch out into new areas of the entertainment industry.
In 2005, Knight and his mother moved to Los Angeles, California, where he was signed by the Osbrink Agency. Since then, he has worked consistently in both film and television, with a wide range of credits to his name. Some of his notable roles include guest starring spots in CBS' "CSI: Miami" and ABC's "Grey's Anatomy," as well as co-starring stints in ABC's "Detroit 187," Fox's "Lie to Me," and TNT's "Dark Blue." In addition to his on-screen work, Knight has also done commercial and voiceover jobs for prominent brands such as Verizon, Home Depot, Best Buy, and McDonald's.
Knight has also worked on looping projects for several films, including "Alvin and the Chipmunks," "The Rookie," and "Mean Girls II." His first film was Mario Van Peebles' "We the Party," marking the beginning of his film career.
