Jenna Coleman has confirmed in an interview with Radio Times that Series 9 of Doctor Who will begin filming in January 2015:
“I’ve been working too hard. There’s not even time for auditions or anything. I’m filming till October.
“They [Doctor Who] start filming in January.”
Coleman has been rumoured to be departing the show in the Christmas Special, and her comments her are vague enough as to not reveal anything more – when the ninth series starts filming in January (presumably with Peter Capaldi), will Coleman still be in the TARDIS?
Series 9 of Doctor Who is expected to be a full series, and will air in late 2015.
