Many thanks to a poster over at C2020 who managed to find this article - "El cine se fija en Marchena para rodar la adaptación de 'La piel del tambor'"
For non Spanish speakers, 'La piel del tambor', is the book the "The Seville Communion/Man from Rome" is adapted from. It seems that some of the filming will take place in Marchena, located in the Province of Sevilla. Andalucía. I expect there will be other locations, but I thought this was interesting given the fact part of my spanish course took us 'virtually' to parts of Andalucía. Now my interest is piqued.
Following is a short news report (in Spanish) from RTV Marchena about the production and location:
"Una vez más, Marchena se acerca al mundo del cine y los rodajes"
I managed to take a very 'ordinary' screencap of some filming for an advertisement mentioned in this news article, but there is more to see in the video clip. (I think this possibly could be the Church Fthr Lorenzo Quart is sent to …)
Enjoy ...
