Boris Karloff
Karloff is most identifiable with horror movies and his three portrayals of Frankenstien's monster. But he had a love and understanding of fairy tales and children's stories and his narration of this is one of his greatest. Add to that the artistry of Churck Jones (yes, there were scenes when the Grinch reminded me of Bugs Bunny), and this is one of the all time great Christmas Cartoons.
