The Return of the King (1980) Movie Review
The animation is typical of the early 1980s, round faces and bulbous noses, wide expressions, and oversized eyes. And lots of singing: "Where there's a whip, there's a way" is a guilty pleasure classic.
Still, the film is hardly outstanding, though it's a mite better than Bakshi's muddy film. Reasonable voice talents, including John Huston as Gandalf, help matters considerably.
