A term that Alan Rickman fans use to refer to him. Rickman, known most famously for his role as Professor Snape in the Harry Potter movies, posesses a voice that has been described variously as: melancholy, seductive, disdainful, languid, honeyed, and velvet baritone.
This nickname is also reinforced by Rickman having played the role of Metatron in the movie "Dogma". Metatron was known as "The Voice of God."
"When I heard the Voice say 'Turn to page 394' in the Harry Potter trailer, I melted into a puddle on the floor."
