The BBC have confirmed that "An Adventure in Space and Time" will be broadcast in the UK on Thursday 21 November 2013 at 9pm on BBC 2. The synopsis reads:
This special one-off drama travels back in time to 1963 to see how Doctor Who was first brought to the screen.
Actor William Hartnell felt trapped by a succession of hard-man roles. Wannabe producer Verity Lambert was frustrated by the TV industry’s glass ceiling. Both of them were to find unlikely hope and unexpected challenges in the form of a Saturday tea-time drama, time travel and monsters!
Allied with a team of brilliant people, they went on to create the longest-running science fiction series ever, now celebrating its 50th anniversary.
