Bob Cratchit miscast
Perhaps the only flaw in this version is David Warner as Cratchit. He is much too tall, strong, and majestic to play this meek, downtrodden character, plus his face looks like a psychopath. Every time Cratchit was on screen I saw Jack the Ripper, Master Control Program, Chancellor Gorkon, or Gul Madred.
I suppose it could be worse--imagine Arnold Schwarzenegger as Cratchit. "Come on, Scrooge! You got what you want. Give those people Christmas!" "I'll be back on December 26." "Get your ass to Camden Town." "Come with me if you want Tiny Tim to live." "Money pleases you, Scrooge, so grant me one request. Grant me Christmas day off! And if you do not listen, then to HELL with you!" "I'm not a pervert! I just was looking for a Christmas turkey!" And without any changes: "Doesn't anybody die any more?"
Or the following dialogue:
Scrooge: What's the difference between you and I? [sic]
Cratchit: The difference is: I'm just going to celebrate Christmas.
