Doctor Who special celebrates 50th anniversary
- 23 November 2013
Doctor Who fans around the world are waiting to watch the show's 50th anniversary episode, The Day of the Doctor, on Saturday night.
Doctor Who boss Steven Moffat said: "It's the most ambitious episode we've ever done."
It's being shown at the same time in over 90 countries!
The episode is also being screened in 3D in more than 1,500 cinemas across the world, including Australia, Russia, Brazil, Ecuador, Spain and Sweden.
The 50th anniversary adventure stars Matt Smith, David Tennant and John Hurt as different incarnations of the Doctor.
Jenna Coleman plays companion Clara Oswald, while Billie Piper returns as Rose Tyler.
The episode also features the Daleks and the return of shape-shifting aliens the Zygons, who first appeared in 1975.
The story involves a mystery at London's National Gallery in the present day, as well as "a murderous plot" in Elizabethan England in 1562.

I am a big fan! It is my birthday today so I am having a Doctor Who-themed party. It will be so cool. I have a toy Dalek as one of my pressies.

I'm dressing up as Matt Smith and while I watch the episode I'm going to eat fish fingers and custard! For the 50th anniversary I've been watching all the episodes of Doctor Who from 2005 up until 2011 (I've been going for two weeks now!), listening to the Doctor Who theme tonnes of times! Also, I set an alarm this morning and my alarm was the Doctor Who theme and yesterday when coming home from school on the bus I worked out how many hours and minutes it was until The Day of The Doctor airs!

I don't understand what is so amazing about it all. It's just a series about a guy with a magic screwdriver.
