How badly did A Christmas Carol's underperformance hurt? This badly: It's brought down Robert Zemeckis's ImageMovers Digital studio. Disney announced today that the studio will shutter its doors after completing the upcoming Mars Needs Moms; it's been around since 1997, but Carol is the only film the studio made after its 2007 acquisition. Disney is now crossing yet another demographic off its character list: terrifying CG old people. [Deadline]
