I KNEW it!
On a whim, I went to the Wiki of the movie "The Road to El Dorado" which I saw on TV today. http://en.wikipedia.org/wiki/The_Road_To_El_Dorado
Check the last trivia. I KNEW it! I have mini-fic's rattling in my brain now. Since no-one but me reads this, (but you are allowed to, my forum friends!) I might post it.
