Well, certainly the 1951 version is a classic. Alastair Sim makes a marvelous Scrooge. Delightful, really. However, I've always had one little gripe about this version. Actually, it's a big gripe about a thing that should be little but isn't. Tiny Tim. In this version, he's a very tall-y Tim, and it annoys me. Scrooge should not look as if he's about to fall over from the weight of Tiny Tim.
The 1962 Mr. Magoo version? Okay, it's not really in the running, but I had to mention it because when I was four, it was in the running and even that badly animated Ghost of Christmas Yet to Come gave me nightmares.
What about the 1984 George C. Scott version? Yes, yes, the score is heavy-handed and downright silly in a few spots (such as when Belle tells Ebenezer she hopes he'll be happy in the life he's chosen and the music pounds us over the head with the significance of what is to come) but I can forgive it all its flaws because of Scott. I think he's the quintessential Scrooge. And I love David Warner and Susannah York as the Cratchits in this one, and Tiny Tim is actually tiny and very cute and I adore him. This version wins the "brings me to tears" tally, and it's my number one. We just watched this one with the girls on Sunday night, and they loved it.
What about you?
