Thanks for the watchful eye.

Sean Connery is widely identified as Catholic, and there isn't much public info. He did play Catholic roles like in The Untouchables and agitate against anti-Catholic discrimination in Scotland, so that might've been the link.

The religion of John Wayne films is fascinating. He converted to Catholicism, but his great director John Ford was Catholic, a subject explored in the book "The Lost Worlds of John Ford" by Jeffrey Richards.
