Criss, a San Francisco native, previously appeared on five episodes of the short-lived ABC series “Eastwick,” as well as one episode of "Cold Case."
On “Glee,” the young actor (and songwriter) will play Blaine, a gay character from a rival glee club, the Dalton Academy Warblers, who may or may not become romantically involved with Kurt (Chris Colfer). The character is expected to be introduced in the Nov. 9 episode.
