Disney Branded Television has ordered “Primos,” an original animated comedy series created and executive produced by Natasha Kline (director of “Big City Greens,” “South Park”). The story, based on Kline’s childhood experiences with her extended multicultural Mexican American family, introduces Tater, an eccentric 10-year-old girl with big dreams and, unbeknownst to her, a certain “it factor” that makes her exceptional. When her 12 cousins (“primos” in Spanish) move in for the summer, they help her discover just what it is.
