Yep, Scott absolutely nailed Scrooge.
I first read A Christmas Carol when I was in high school, after I had seen a couple of the older movies. None of those actors were Scrooge.
I finally saw the Scott version in the early 1990s. Bam. Scrooge.
Alaistair Sim? Reginald Owen?
Nope. Not Scrooge.
Albert Finney in the musical? Closer...
