kev, I think I found something that you might be interested in, a place where a scene from The Godfather was filmed, that actually still exists!
Remember the "baptism" scene right at the very end of the movie? This is where Michael and Kaye are at a church becoming the "godparents" to Connie Corelone's new baby.
Apparently, this scene was filmed at "Old St. Patrick's Cathedral," located at 260-264 Mulberry Street (also on the Lower East Side -- this is not to be confused with the more modern "St. Patrick's Cathedral" which is at 5th Avenue and 50th St).
Here's an inside pic of Old St. Patrick's:
Hey, that
does look like the place where that scene was filmed! That might be an interesting place to visit.
To be honest, I didn't realize there
was an "Old St. Patick's Cathedral!"
