In DWM 384, both DEREK JACOBI and JOHN SIMM speak exclusively about breathing new life into the Doctor's old nemesis...
"I've tried to explain to my son that his dad is going to be, like, the epitome of evil," John Simm laughs, "but if I say, 'I have a fight with Doctor Who,' and ask him who he wants to win, he'll say Doctor Who! It's one of those opportunities, though, to impress your son in a massive way, and that was just too good to turn down. Julie Gardner was trying to find something for me to do in it, and I kept saying, 'Look, I'm not being painted blue!' And then Julie and Russell T Davies said, 'What about the Master?' As soon as they said that, I was like,'You're kidding? Oh yeah!' I got really excited about it, but I just had to sit on the news. I wanted to tell people, 'I'M GOING TO BE THE MASTER!!!' But it was a secret. Hmft."
Also this issue, there's a preview of the devastating climax to Series Three, Last of the Time Lords, as the Doctor, Martha and Jack struggle to save the Earth from the Master's clutches.
