For Christmas night, NBC is being extra Grinchy, and presenting a rare compare-and-contrast, animation-and-live action doubleheader. First is the classic 1966 toon version, with the animation by Chuck Jones, the story by Dr. Seuss, and the voice of Boris Karloff. Then, at 8:30 p.m. ET, comes the 2000 live-action movie, starring Jim Carrey as an equally rubbery-faced, maniacally grinning Grinch.
