Corbin began appearing in television commercials at the age two, for products such as Life cereal, Bounty, Hasbro, and Nabisco.

By the age of four he was a model with the Ford Modeling Agency in New York. He appeared in print ads for stores such as Macy's, Gap, Target, and Toys R Us, and fashion spreads in Child, Parent, and American Baby magazines, as well as having his image on toys and game packaging. At age six Corbin appeared in his first professional theater production off Broadway playing an abandon homeless mute in the play "Tiny Tim is Dead".
Corbin and his family moved to Los Angeles in 1996 and he quickly landed a recurring role on the television series High Incident (1996). He continued to land small roles in such feature films as Soldier (1998) with Kurt Russell, Mystery Men (1999) with Ben Stiller, William H.

He then attended the Los Angeles County High School for the Arts as a theater major, this time following in his mother's footsteps who attended New York City's famed High School of Performing Arts. While in his freshman year Corbin was cast in his first lead role in the feature film Catch That Kid (2004). Back in school in his sophomore year he played the lead role of Ren in the musical "Footloose" and the role of Sonny in the musical "Grease".
