Tonight's Doctor Who Christmas Special, "The Runaway Bride", is effectively being given a free trailer as part of the news headlines on BBC Radio 2 this Christmas Day morning. The hourly bulletin at 9am featured as its last article a report by entertainment correspondent Colin Paterson on the "news" that Catherine Tate will be joining the TARDIS crew for this evening's special.
Paterson reported how, although set at Christmas, the episode was actually shot on some of the hottest days of the summer in Cardiff. An interview clip with Tate was played, saying how she had felt sympathy for the extras who had had to dress in coats, hats and scarves to give the impression of it being winter.
Listeners were then reminded that "The Runaway Bride" can be seen tonight at 7pm on BBC One.
