The Knights of Columbus are heavily promoting this movie, and tying it to the current struggle for religious freedom against the oppressive regime of the Kenyan anti-Christ.
Crossing my fingers that it will become a cultural metaphor for opposition to the regime.

I was shocked to read the US supported the slaughter of the Cristeros:
By contrast, later in the war the Calles government was supplied with arms and ammunition by the U.S. government. In at least one battle, American pilots provided air support for the federal army against the Cristero rebels.
