Every year I like to watch the 1951 version of A Christmas Carol in black and white. It is, IMO, the definitive version of the Dickens' story. The black and white cinematography only enhances the story about the plight of the poor in London at the time and the actors, especially Alistair Sim, have amazingly expressive faces throughout.
This version (below) is complete, showing portions often not seen when it is played on television.
After enjoying the movie, stop by this website to read all about the movie and how it was made.
