THE MASK OF ZORRO is a fun movie, but not for all.
Violence is the biggest issue in the film. Swordfights, duels, deaths, and big flashy explosions populate this adventure. One scene very briefly shows a man's decapitated head and hand floating in water. The violence is mostly without gore. Language consists of one use of "d**n". Sex consists of one very brief shot of several men's bare behinds, and one playful scene where Elena's top is cut off (but no nudity shown at all).
It's a fun, rousing adventure that makes a good family movie, but I wouldn't show it to sensitive kids.
