In 2014, Big Finish started a new range of Doctor Who stories, bringing back original cast members from the 1960s eras in order to tell new stories: they're audio tales in black and white! The TARDIS crew encounter a dangerous race of clones, planning to drag the Solar System into an endless war. This range of era-authentic new stories has been hugely popular with fans, with a further two series already commissioned. Peter Purves is known to generations as one of the all-time great Blue Peter presenters, but this came after an acting career which he's returning to here to play both the Doctor and 1960s companion Steven Taylor. Jean Marsh is a legend of stage and screen, while also being one of the forces behind Upstairs, Downstairs. Guest star Dan Starkey currently plays fan favourite Strax the Sontaran on the TV version of Doctor Who. Fortunately, as they're a clone race he's perfectly cast for this story! CAST: Peter Purves (Steven/The Doctor/Narrator), Jean Marsh (Sara Kingdom), Dan Starkey (Corporal Ellis/Slite/Shrok/Stack/Commander), Jemma Churchill (Captain Papas), John Banks (Corporal Gage), Rosanna Miles (Tinder/Human Soldier).
