As 99.9% of Planet Earth is keenly aware, An Adventure in Space and Time, the 50th anniversary biopic written by Sherlock co-creator Mark Gatiss and starring David Bradley as the first Doctor William Hartnell, charts the sci-fi drama’s early years.
 

In addition to Bradley, also cast are Claudia Grant as Carole Ann Ford, who played the Doctor’s granddaughter Susan Foreman, Jemma Powell and Jamie Glover who portray Jacqueline Hill and William Russell, the First Doctor’s companions Barbara and Ian. Sasha Dhawan as director Waris Hussein and Jessica Raine (Call the Midwife) portraying producer Verity Lambert. Brian Cox also appears as Sydney Newman, Head of Drama at the BBC in 1963.
 

In addition to Gatiss’ drama, the Doctor Who 50th anniversary special ‘The Day of the Doctor’, starring Matt Smith, David Tennant, Jenna Coleman, Billie Piper and John Hurt, will air worldwide on November 23, 50 years to the day after the first transmission of the series back in 1963. While the trailer, which premiered last night on BBC One following Strictly Come Dancing, brilliantly shows all of the Doctors as they first appeared on screen, including William Hartnell in colorful grandeur for the very first time, it does not include any actual footage of the 50th anniversary episode. Departing Eleventh Doctor, Matt Smith reminds us all that “I have been running all my lives. Every second of every minute of every day for over 900 years. Our future depends on one single moment of one impossible day. The day I have been running from all my life. The Day of the Doctor.”
