Dr. Who: A Christmas Carol

When the annual “Dr. Who: A Christmas Carol” special airs Dec. 25 on BBC America at 9 p.m. (eastern), prepare for a Time Lordian twist on the Dickens’ holiday classic. The plot centers on The Doctor’s attempt to save the soul of an old scrooge to save Rory and Amy (who are on a spaceship about to crash). The special will feature an appearance by classical vocal star Katherine Jenkins and Harry Potter’s Michael Gambon. It also marks the first time American audiences will be able to see the annual “Dr. Who” Christmas special on the same day as British fans. Of any TV series ever, what’s your pick for the best Christmas episode ever?
