At 1:14 into the movie during the scene where they lead the prisoners to the top of the Mayan temple, there is a shot of the crowd cheering. Hit the pause button (at 1:14) and look directly in the center at the woman standing alone on the steps. She's white with gray hair and wearing a skirt and tank top! Now, go behind her into the crowd and you will see 2 more white women, one who resembles Jackie Kennedy with long black hair and a pillbox hat! It looks like maybe someone's aunts or wives wanted to be in the movie somehow and this is how they slid them in.

VERY obvious!
