I absolutely loved this movie, very under-rated IMO, so nice to see a very new background environment for an action movie.
It also depicts the astounding amount of slavery and raiding and human sacrifice in indigenous societies. An inconvenient fact given the narrative promoted today.
Not sure if indigeneous people's in Canada and the US participated in human sacrifice etc., But the movie was about the Mayans, who primarily lived in Guatemala.
I did visit the Mayan city in Tikkal, Guatemala and saw the ancient ruins, It was quite fascinating. Infact, Tikkal still has Mayan people and you can see them still wearing traditional clothing, selling traditional crafts etc., Quite fascinating.
