Zygon creator Robert Banks Stewart, who wrote 1975’s ‘Terror Of The Zygons’ and 1976’s ‘The Seeds Of Doom’ for the show, let slip to Digital Spy that the sucker-faced shapeshifters won’t be the only classic terrors making a return for the Doctor Who 50th Annviersary episode.
“The Zygons are in there with all the others – particularly the Daleks and the Cybermen,” said Banks Stewart.
“[But] nobody yet knows what the plot of the 50th will be – Steven Moffat and his team in Cardiff, they are quite rightly keeping it all secret.”
Doctor Who is airing now on BBC One. Doctor Who Series 7 Part 2 will be available to own 20 May 2013 – pre-order it on Blu-ray for £21.50 or on DVD for £17.75 from Amazon.co.uk.
