Frank Finlay's performance as Jacob Marley is considered one of the best versions onscreen, alternately terrifying, tormented, and deeply remorseful.
The sets, music, and special effects are very high-quality for a TV movie, particularly the future scenes.
Ebenezer Scrooge: Tell me, Spirit... Will he [Tiny Tim] live? Ghost of Christmas Present: I see an empty place at this table. I see a crutch without an owner, carefully preserved. If these shadows remain unaltered by the future, the child will die. Ebenezer Scrooge: No. Say he'll be spared. Ghost of Christmas Present: If these shadows remain unaltered by the future, none other of my species will find him here. But if he is to die, then let him die...! AND DECREASE THE SURPLUS POPULATION! Ebenezer Scrooge: You use my own words against me? Ghost of Christmas Present: Yes! So perhaps, in the future, you will hold your tongue until you have discovered where the surplus population is, and WHO it is. It may well be that, in the sight of Heaven, you are more worthless and less fit to live than MILLIONS like this poor man's child!
