It's not every day a science fiction franchise reaches 50 years old, let alone still has it's original television series still in production (okay, so it had a hiatus in the 80s until 2005, but shush!) but Doctor Who defiantly continues onwards, despite what some of the more old school BBC bosses of the 1960s predicted.
For those not in the know, Doctor Who sees an enigmatic character known only as the Doctor travel the galaxy in his space-time machine, the TARDIS (Time And Relative Dimension In Space). The Doctor hails from the planet Galifrey, home of an ancient and advanced all-but-extinct race known as the Time Lords.
Tonight, sci-fi fans across the world will be glued to their screens as the Eleventh Doctor teams up with his previous incarnation to confront his darkest secret. Check out the fantastic trailer below:
The 50th anniversary special, Day of the Doctor, is being simulcast around the world, so be sure to check your TV guide for the broadcast time and channel in your area.
