It's probably the best-known version of A Christmas Carol on film, but sadly this 1951 rendition has aged terribly. Watch it today and you'll immediately note the atrocious sound quality and that the special effects aren't any better than the version made in 1938. Alastair Sim is appropriately grumpy as Scrooge, but he adds little to the role that any other actor has brought to it. Frankly, of all the versions of Carol that are out there, this is the first I'd skip.

Aka Scrooge.
