Question About For Greater Glory Movie

I know a lot of people in this group have lived or traveled in Jalisco and the Los Altos region.  Sadly, I am not one of them.  I am curious if anybody recognized any of the locations that appeared in the film "For Greater Glory"?  I tried searching on the Internet for specific information regarding filming locations but nothing turned up.  I read some of the battles were filmed at actual locations.  Also, what happened to the expert on the Cristero Rebellion, Steven Hernandez?  He did a Masters thesis on it.  I would love to hear his opinion about the film.  I remember a long time ago he would leave posts on Nuestros Ranchos that were really interesting.
