Over the years the supernatural beings in adaptations of A Christmas Carol have tended to grow more monstrous. Now with CGI I’m sure sure we’ll see many actors in make-up as them again. On the other hand, it’s not too surprising that when you make a comic version of the story with the main star of Ghostbusters that you’d amp up the scary/funny ghosties.
Meh, I’ll stick with Alastair Sim.
