That's what I notice in almost any Kenyon & Mitchell movie with crowds: everyone wears a hat. Here, that's most of what you see, because it seems to have been shot from a second story window across the street, looking down. That allows you to see the congregants' faces, of course, but especially their hats.
If, like me, you're wondering what a pro-cathedral is, you can find out here, because I looked it up for you.
"A pro-cathedral or procathedral is a parish church that temporarily serves as the cathedral or co-cathedral of a diocese, or a church that has the same function in a Catholic missionary jurisdiction (such as an apostolic prefecture or apostolic administration) that is not yet entitled to a proper cathedral."
You're welcome.
