The Netflix movie "Rez Ball" is inspired by real-life experiences on the Navajo reservation, specifically drawing from the book "Canyon Dreams" about the Chinle High School Wildcats, and director Sydney Freeland's own experiences playing basketball growing up on the reservation. While not a direct adaptation of either source, "Rez Ball" draws upon themes of community, resilience, and the importance of basketball in Native American culture. The film portrays the fictional Chuska Warriors, a high school basketball team navigating tragedy and their own expectations, highlighting both the struggles and triumphs faced by individuals and communities within the reservation.
