Dueling Movies: This film came out it close proximity to the fellow 1998 swashbuckler The Man in the Iron Mask. Both feature older versions of the classic hero coming back into action in order to take down a corrupt ruler and mentoring a younger hero in training.
Both Don Diego and his daughter Elena are played by Welsh actors, Alejandro is a Mexican played by a Spaniard, and both villains (the probably Spanish Montero and the French Armand) are played by Englishmen.
As a point of interest, this is the first Zorro movie where the hero is played by a real Spaniard as in the books. Unfortunately, this version is Mexican.
Follow the Leader: This film came out in a wave of modern swashbuckler adventure films that updated classic stories following the success of Robin Hood: Prince of Thieves, with bonus points for also having a love ballad/pop song made for it that's weaved into the orchestral score . Although in terms of its story whilst The Mask of Zorro may have inspired the film version of The Count of Monte Cristo; Zorro itself seems to be a retelling of the Monte Cristo story (it's actually a retelling of The Curse Of Capistrano).
Throw It In: Anthony Hopkins was very proud of the work he did mastering the bullwhip and insisted they let him show off a bit. The scene in the cave where he's extinguishing candles with the whip? That was Hopkins.
In Ted Elliott and Terry Rossio's original draft of the screenplay, Don Diego was not killed, and lived to tell the story of Zorro's adventures to his granddaughter.
You Look Familiar: Pedro Armendariz Jr. plays both Don Hector and Governor Riley. In addition Tony Amendola plays Don Luis and Father Quintero, the name of the villain in the Tyrone Power film was Don Luis Quintero.
