The kid in Mummy Returns wasn't too bad; he was fairly intelligent for an action movie kid, but not overly so either.
Mask of Zorro was awesome, but everyone needs to watch the Tyrone Power Mark of Zorro (the second version of the original film), which I just got from Amazon for $10. The original novel, The Curse of Capistrano, is great too.
Zorro has always been my favorite hero. Ironically enough, I used to watch Zorro dubbed into Spanish when I was little, which is amusing considering that it was an American show about Spanish controlled California based on stories written by an American who didn't really know much about the time period.
