The studio fostered many series: The Dead End Kids and Little Tough Guys action features and serials (1938–43); the comic adventures of infant Baby Sandy (1938–41); comedies with Hugh Herbert (1938–42) and The Ritz Brothers (1940–43); musicals with Robert Paige, Jane Frazee, The Andrews Sisters, and The Merry Macs (1938–45); and westerns with Tom Mix (1932–33), Buck Jones (1933–36), Bob Baker (1938–39), Johnny Mack Brown (1938–43); Rod Cameron (1944–45), and Kirby Grant (1946–47).
