Sure, I watch the Dr. Seuss' How the Grinch Stole Christmas film a few times each year about this time, but I keep going back to the original book by Dr. Seuss (born Theodor Seuss Geisel) throughout the year.
Besides being a great read, this is (in my mind) one of the best warm-up books for voice actors.
See? It all comes back to acting ...
