Filmation was undergoing a period of transition in the early 80's. Tarzan, Lord of the Jungle, had been in perpetual rerun for a number of years, but CBS kept him around long enough to share an anthology package with two other legendary heroes, The Lone Ranger and Zorro, the latter of whom made his return to television in 1981, with the other two series' episodes being trimmed in order that all three could fill a hour-long block. Small wonder, then, that The New Adventures of Zorro was cancelled after 1 season, and was one of the last to have the famous producers' wheel in the opening credits.
For what it's worth, actor Henry Darrow (ex-High Chaparral) was the voice of Zorro in this series, but a decade later, he'd co-star as Zorro's father, Don Alejandro, in a live-action revival that aired on the Family Channel. Darrow replaced another TV legend, Efrem Zimbalist, Jr. (ex-The F. B. I.), who'd left after 1 season.
