The powerful words of that carol that gave me chills in 2014 come of course from the poem, “Christmas Day,” by Henry Wadsworth Longfellow, and the backstory behind the man and his poem are the focus of a new movie by Sight & Sound, I Heard the Bells. Known for their biblically based theatrical performances in Branson and Pennsylvania, this is Sight & Sound’s first movie, and they hit it out of the park.
