Robert Zemeckis is back with another motion captured, slightly creepy, animated movie. This time he’s taking on the Dickens classic “A Christmas Carol” with Jim Carrey starring in multiple roles. It looks like a fine take on the classic story but it has two huge obstacles to overcome. First is how do you make the umpteenth version of “A Christmas Carol” original and it’s coming out in the same timeframe as Avatar; the two are almost guaranteed to be compared in terms of realism and tech. Check out the trailer below and see for yourself.
