Welcome to the forum. There are a couple of movies dealing with the subject you ask about, one of which is Mel Gibson's Apocalypto. It is quite a good adventure/chase movie but it is in subtitles as authentic language is used. -- AlMy top 5:
Harlech song (with Zulu bass section) in Zulu.
Minstrel Boy song in Rough Riders.
Charge at the end of Last Samurai.
Gunfight at the OK Coral in Tombstone.
The Battle of Agincourt in Branagh's Henry V.
Also: any scene from The Vikings.
Love to talk about military history movies; like most of them!
Q: Are there any good movies about the Aztecs or even Incas or Mayans?
Best wishes
