NBC has brought Damon Wayans back for a guest-starring role in the Season 3 premiere of its mockumentary series St. Denis Medical. Wayans will appear opposite David Alan Grier, his former castmate from the sketch comedy series In Living Color, marking an on-screen reunion for the pair. He is set to play Dr. Highland, described as a charming but pompous new doctor on the show. The network also released a first-look photo of Wayans in character. Wayans, known for his work on My Wife and Kids and Lethal Weapon, joins a series that follows the staff of a struggling hospital. Grier is a regular on St. Denis Medical, and the reunion brings together two actors who worked together on the landmark Fox sketch show in the early 1990s. The episode will serve as the Season 3 premiere, though no air date has been announced. The booking continues NBC's pattern of tapping established comedy stars for the series, which has built its cast around veteran performers. The reunion adds a familiar comedic pairing to the show's mockumentary format, which blends workplace humor with character-driven storylines.
