Before watching the movie:
Although this film reintroduced audiences to Zorro in the 90s, I know it’s not exactly an origin story, but in fact a legacy torch-passing. I’m not familiar enough with the story of Zorro to know why they couldn’t make the original Zorro the man they wanted him to be, but maybe it’s just more about the story they wanted to tell.
I’m not sure, but I think this is the movie that made Antonio Banderas a star, though a quick Wikipedia lookup says no. It does seem to be his break into very mainstream films, though.
