The Master, the Doctor’s long time foe, has been off screens for over four years now – last seen in John Simm form, blasting lightning at Rassilon in The End of Time.
His return has been rumoured several times since, but the renegade Time Lord still hasn’t returned – and on his Brazil publicity tour, writer Mark Gatiss spoke on the chances of a Master return alongside new Doctor Peter Capaldi.
“I think anything is possible, but with this new Doctor, I think it’s important not to get stuck on old preferences. When I was little, Tom Baker took over as Doctor and had a complete change of monsters. The Zygons and the Krynoids are fantastic. It’s always nice to have new things.”
