The perennial holiday classic A Christmas Carol gets the high-tech, big budget treatment on November 6. Jim Carrey stars as everyone's favorite curmudgeon, Ebenezer Scrooge, as well as the three ghosts who pay him a visit. To bring the story to life, director Robert Zemeckis (Back to the Future) utilizes the innovative motion-capture animation technique, which he previously used in The Polar Express and Beowulf. In this MakingOf.com clip, Zemeckis and Carrey (along with co-star Colin Firth and the movie's producers) discuss what audiences can expect to feast their eyes on in this latest adaptation of A Christmas Carol.
