I was struck by an interview he once gave to Charlie Rose, in which the sarcastic loud-mouth was revealed to be a quiet, thoughtful soul with a deep appreciation for the contemplative life. When he was a young man, Boyle read Thomas Merton's "Seven Storey Mountain," and decided to enter religious life. He studied for a time with the Christian Brothers, before leaving to become an actor.
"Holy crap," indeed.
Requiescat In Pace.
