It's been a fun ten weeks, but now the end is finally approaching. It's time to begin bidding farewell to Peter Capaldi as the 12th Doctor, Michelle Gomez as Missy, Steven Moffat as showrunner and potentially Pearl Mackie as Bill Potts too. As Doctor Who series 10 draws to a close we begin the two-part finale with World Enough and Time - written by Moffat and directed by Rachel Talalay, who previously directed the two-part finales for both series eight and nine. As well as bringing back the original Mondasian Cybermen to screens, World Enough and Time also features the much-publicised return of John Simm as the Master, making this the first multi-Master story put to screen.
