This version of "A Christmas Carol," directed and written by Robert Zemeckis, has a very hard time justifying its existence. The digital animation is bizarre and garish, just as it was in Zemeckis's "The Polar Express." Jim Carrey — famously not British — voices not just Scrooge but also all three ghosts, with different accents for all of them (though, of course, Ghost of Christmas Yet to Come, doesn't speak; Carrey's body was used as the model for the character). The only voice performance with any zip behind it is Colin Firth as Scrooge's nephew Fred. This one is not a musical, but it seems kind of self-conscious about that and uses Christmas carols constantly to try to liven up the soundscape. It doesn't work.
