Never even heard of the 2001 version. (And I've seen a lot of obscure versions.) How does the George C. Scott version rate for accuracy?
The 1970 musical Scrooge gets extra points from me for Alec Guinness as Marley, and Ebeneezer's brief visit to his own personal hell. Although I think someone involved in the production was projecting their personal kinks just a tad...
The Mickey Mouse version gets a little disturbing, since the Little Pigs are in the cast, yet a roast pig is seen in a holiday feast. What the hell?
