There are quite a few "Scrooge" movies, but I do have a particular favorite:
"A Christmas Carol" with George C Scott. This one is interesting for a few reasons, not the least of which is that it's a "Made-for-TV" version of ACC. It's formatted for television screens of the time. Another reason it's so interesting is George C Scott's portrayal of Scrooge. He's such a powerhouse actor but he somehow manages to keep the story at the front as opposed to keeping his performance at the front. It's such a good performance, you really don't care that his English accent is less than perfect. Also, David Warner in one of his non-villain roles is fantastic as Bob Cratchit with Suzanna York (Superman's Mom) as his wife. It's a pitch-perfect version, it's shot well, and otherwise checks every box that a great holiday classic should.
