Showrunner Steven Moffat has dropped a hint that the upcoming 50th anniversary special of "Doctor Who" could very well "change the narrative" of the series. Talking about that episode with Broadcast Now, he says:
"A big episode can be anything that moves the plot along. My main thing [when writing the script] was that as much as we celebrate the past, we can change the narrative. You can't tell a story by being frightened about it."
The 76-minute special will be simulcast globally in three weeks time on November 23rd. There is still no release as yet of a trailer containing actual footage from the special, but the British Board of Film Classification (BBFC) have recently classified a new 70-second trailer which should appear in coming days.
The BBFC have also classified one of the extras for the special - a nearly four-minute piece called "The Last Day" which is expected to be a 'minisode' that ties in with the special.
Additionally, the certification and length of the The Day of the Doctor has been outed. The special is classified ‘PG’ for containing "mild violence and threat."
Moffat also spoke about next year's first full season of the show starring Peter Capaldi in the role of the Time Lord. Moffat says they are committed to producing "at least" 13 episodes in 2014.
