Gladiators of the Desert (2017)

In Chile, where European football (i.e., soccer) is the dominant sport, Coach Carlos Zuniga offers at-risk teenage boys a unique opportunity to learn and play American-style football. He struggles through a grueling season trying to balance teaching the unfamiliar game to his players while fighting for recognition and funding from city officials who have no interest in the sport.

Unfortunately the movie Gladiators of the Desert is not yet available on HBO Max.
