The BBC have announced that this year's Christmas Special will be broadcast on BBC1 at 5.15pm - making it the earliest so far. Might this mean that it is a bit less scary for younger viewers? Judging from the trailer, I wouldn't have thought so. The US and Canada are getting it at 9pm (Eastern), and Australia (on the 26th) at 7.30pm. It's the expected 60 minutes long.
