Doctor Who showrunner Steven Moffat has confirmed that a scriptwriter from the classic series of the programme will pen a script for the upcoming series.
This will be the first time a writer from the original series, which ran from 1963 to 1989, will contribute to the revived series, launched in 2005. One director, Graeme Harper, has contributed to both runs, helming episodes in 1984 and 1985, and from 2006 to 2009.
Moffat announced the news at a panel at New York Comic-Con, and confirmed it in an interview with Comic Book Resources.
There is no confirmation yet as to whom the writer will be.
Other writers already confirmed for the upcoming series include Frank Cottrell-Boyce, who wrote the 2014 story In The Forest Of The Night, Sarah Dollard, who wrote last years Face the Raven, vintage contributor Mark Gatiss and newcomer to Who Mike Bartlett, best known for Doctor Foster.
Series 10 is due for transmission in the spring of 2017.
