There were many television adaptations of A Christmas Carol aired during the early days of television, many performed live. The earliest existing version is from 1949 and was hosted by Vincent Price, who appears onscreen, reading from a well-worn copy of the book.
The adaptation is simple and basic, and the production values are mediocre. Nephew Fred, Belle, Fezziwig, and Old Joe are all gone from this version. So are many of Dickens' heavy themes.
Overall, this version is more for fans of Vincent Price or those wanting to see most of the adaptations of this story. There's better versions.
