I work in publishing and received an email from his assistant one day saying, “Denzel wants to talk to you.” He was working on a foreword for a book. He called personally to ask that we use a different Bible translation (he wanted the KJV)than the one that was used to go along with his Foreword. I was impressed.
Most interesting! Thank you for that.
Given your post, I'd recommend watching him in "The Book of Eli". It's a post-apocalyptic movie that has to be watched to the end to get the full impact of the story. It has a pretty remarkable "twist" that will stay with you.
I think I read somewhere that he was a preacher’s kid, had his time of rebellion, then woke up.
