movie from before 2010 where people in a wigwam have to strip to enter

When a willful young man tries to venture beyond his sequestered Pennsylvania hamlet, his actions set off a chain of chilling incidents that will alter the community forever.

After they find buried treasure, four hapless brothers from the countryside discover that changing their fortunes will take more than gold.

Informed by radical anthropology (and Raquel Welch's furkini in 1 Million Years BC) 10000 BC follows a group of women taking part in a sex strike for meat. A satire of simplistic binary men vs women sex wars politics using corny 60s epic cinema aesthetics, with a surprisingly easy resolution and a queer romance. It was created with a crew of women and LGBTQ+ people.
