The original version of "Lord Of The Rings" made by Warner Brothers in 1944 has been recently unearthed by film scholars. The casting is very inspired, Peter Lorre as Gollum is excellent.
Two thumbs up!
There was a 1978 cartoon version, one of the voices was John Hurt. The scenes from the Peter Jackson version are close to being the same from the cartoon. He must of used it for inspiration.
