To celebrate 50 years of Doctor Who here are 50 fantastic, fascinating facts about one of the best-loved TV shows in history.
1. The original Daleks: The original Daleks were controlled from the inside by short operators who had to manipulate their eyestalks, domes and arms, as well as flashing the lights on their heads in sync with the actor's voices. John Scott Martin, one of the original Dalek operators, once said: "If you were related to an octopus then it helped!"
2. Title sequences: There have been around 12 different title sequences. The theme music was originally composed by Ron Grainer and created by Delia Derbyshire at the BBC Radiophonic Workshop. Since then there have been a vast variety of remixes of the theme music. Matt Smith (the 11th Doctor) even got up on stage at the 2010 Glastonbury Festival to perform a version of the music with the band Orbital.
3. Home: The Doctor has visited many different planets, but his home planet is called Gallifrey.
4. Medical doctor: The Doctor actually is a doctor! In a sickbay in the 1967 story The Moonbase, the Doctor was asked, "Listen, are you really a medical doctor?" He replied, "Yes, I think I was once, Polly. I think I took a degree once in Glasgow. 1888 I think. Lister."
5. Bow ties: "Bow ties are cool" - that's what Matt Smith said in his first appearance as the Doctor. Bow tie sales shot up by 94% within a month at one high street store!
6. Gadgets: The Doctor has an array of gadgets, including the sonic screwdriver - which has many uses including the ability to unlock almost anything - and the psychic paper, which can bamboozle people into seeing whatever the user wants them to see printed on it.
7. Red Nose Day: In 1999, a four-episode special of Doctor Who called The Curse of Fatal Death was made for Red Nose Day. It featured big name stars such as Rowan Atkinson (Mr. Bean), Richard E. Grant, Jim Broadbent, Hugh Grant, and Joanna Lumley as The Doctor.
8. Regeneration: The regeneration effect, used for when one Doctor changes into the next one, was created at the end of the first series by accident! A faulty mixing desk allowed the image of William Hartnell (the first Doctor) to be overexposed almost to white so that Patrick Troughton (the second Doctor) could be put in his place before the effect faded again.
9. Multiple Doctors: The 50th anniversary episode will not be the first time more than one Doctor will have appeared in the same episode. For the show's 20th anniversary, a feature-length special called The Five Doctors was created, featuring the first five Doctors.
10. Doctor's real name: The Doctor's real name remains a complete mystery to all but a very small number of individuals including The Master, River Song and Clara Oswald.
11. Sherlock-tor Who? The character of the Doctor was partly inspired by Sherlock Holmes. Comparisons have been made between the Doctor and the fictional detective. In fact both the fourth and eleventh Doctors have dressed up as Sherlock Holmes in episodes of Doctor Who.
12. The biggest fan: A six year-old-boy called Flynn was named as the UK's biggest Doctor Who fan after a nation-wide search by the Doctor Who Adventures magazine this year. He won the title as a result of his monster themed tea-party idea, and a letter explaining how much he loves the show. Both he and his twin brother would like to be future Doctors.
13. Celery. Yum! The fifth Doctor wore a piece of celery on his lapel because he was allergic to a certain gas in the Praxis Range. Once the celery turned purple he would eat it and it would save him.
14. What's the time, Weeping Angels? The Weeping Angels are based on the children's game What's the time, Mr Wolf?
15. The Whomobile: (Not to be confused with the Batmobile) the Whomobile was a special vehicle created by the third Doctor and first appeared in the episode called Invasion of the Dinosaurs. It was capable of speeds of 105mph and even appeared on Blue Peter!
16. Matt's outfit: The original costume ideas for eleventh Doctor Matt Smith's look were very different from his iconic tweed jacket and bow tie. Some of the costume ideas included a buccaneer pirate-style one, which Matt wasn't very keen on.
17. Lost and found: The original pilot episode, which was thought to be lost forever, was rediscovered in 1978 in a mislabelled film can.
18. The key to the TARDIS: The distinctive TARDIS sound effect was originally created by simply rubbing the bass strings of a piano with a key. This sound was then modified by the BBC Radiophonic Workshop and then became the well-known sound effect that they still use variations of today!
19. Rewriting history: During his travels throughout time the Doctor has met and in some cases befriended plenty of historical figures, including: Leonardo da Vinci, William Shakespeare, Albert Einstein, Charles Dickens, Queen Victoria, Elizabeth I and Winston Churchill.
20. Top seller: Doctor Who is currently BBC Worldwide's biggest selling TV show around the world.
21. Lady Doctor? When the original series was struggling with ratings in the 1980s, the show's co-creator, Sydney Newman, wrote a letter to BBC One Controller Michael Grade, suggesting some radical new ideas for the show, including the introduction of a Time-Lady (a female Doctor).
22. Most-watched episode: City Of Death featuring the fourth Doctor, scored the highest viewing figures of any Doctor Who episode in the UK, drawing in over sixteen million viewers. The second highest is Voyage of the Damned starring Kylie Minogue and David Tennant as the eleventh Doctor, which on its original airdate was watched by 13.31 million viewers, and as of November 2013 still has the highest viewership of any episode since the show's return in 2005.
23. TARDIS-teroid: Asteroid 3325, a main belt asteroid discovered in 1984, is named TARDIS after the Doctor's time/space machine.
24. The Young Doctor: Matt Smith is the youngest actor to play The Doctor, starting at 26 years old.
25. Former fanboys: Both Peter Capaldi (the twelfth Doctor) and David Tennant (the tenth Doctor) were huge fans of Doctor Who growing up. David Tennant's nan even knitted him a scarf like the fourth Doctor's, and Peter Capaldi regularly sent letters, and essays into the Doctor Who production office, and wanted to run the Doctor Who fan Club.
