Zorro was originally created by pulp writer Johnston McCulley in 1919 and was set during the era of Mexican rule of California (1821-1846). Don Diego de la Vega, a nobleman living in Los Angeles, adopted the identity of the masked outlaw who helped those who were persecuted by tyrannical authorities and other villains. Movie adaptations usually set the time period under Spanish rule.
McCulley’s stories were not always consistent and sometimes contradictory (Zorro might die in one story and alive in the next). Zorro is a cunning foil for those he goes up against. Sometimes his targets are overconfident while others sometimes bumbling. And he delights in giving them their comeuppance. There have been many movies made telling the Zorro story starting in the silent era all the way up till recent times produced in the U.S., Mexico and Europe. There have been both live action and animated television series as well.
One of the more notable ones was Disney’s Zorro that ran from 1957-1959 on ABC. It ran for two seasons before a dispute between Disney and ABC over ownership rights cut the show short. It was kept alive for a series of 4 one hour movies using the same cast. The dispute was resolved but Disney felt it had run its course. In the Disney version, Don Diego de la Vega was portrayed by Guy Williams (later of Lost in Space) for the entire run of the series.
The Disney Zorro used arcs that would span several episodes. The first season was primary with Zorro battling wits with Captain/Commandante Monastario. The second season had several different arcs such as dealing the the attempts to seize California from Spain by a self-made tyrant, dealing with corruption in Monterey, or involving characters that spanned several episodes.
What made Zorro so interesting is that he was clever, a good fencer, employed clever strategy, and rarely did he kill his foes (it did occur but not often by his hand but by some other means). The Disney version also used comedy to lighten the mood, often to good use.
While originally filmed in black & white, the episodes have all been colorized. There are different places you can buy them though the original Disney versions can be expensive. Beware of pirated collections sold through some websites. They simply recorded it from the Disney Channel and is not very good resolution. The Family Channel did a remake called The New Zorro (or just Zorro in some cases)that ran from 1990-1993. It is a worthy successor in its own right though I think the opening theme from Disney’s version is better.
