In the wake of his explosive return in the season 10 finale of Doctor Who, John Simm says he would be open to another turn as the Master. A fellow Time Lord from Gallifrey, the Master is one of Doctor Who's longest serving villains, dating back to the era of Third Doctor Jon Pertwee in the early '70s. The Master was originally portrayed by Robert Delgado, and would go on to be played by Anthony Ainley, Derek Jacobi, and even Eric Roberts.
The latest iteration of the Master was portrayed by Michelle Gomez, who went by Missy to reflect the gender swap of that iteration. It was a surprise when it was announced Simm would return to the role for the first time since the 2010 farewell to the Tenth Doctor, David Tennant, 'The End of Time'.
In an interview with Doctor Who Magazine (via Doctor Who TV), Simm admitted he's unsure he'd be asked to play the role again, but acknowledges he was surprised to get the offer to face off with Peter Capaldi's Doctor.
“You know what, I don’t know. I mean, I wouldn’t have thought in a million years that I’d be back [in 2017], yet here I am talking about it, so never say never. So you never know. This thing called Doctor Who is a machine that just sort of goes on its own. It’s got its own rules. And if they want you back, then great. I would definitely think about it.”
Simm remains cagey on his potential future with the show, but feels lucky to have been part of two different eras of the show, and getting to face off against both the Tenth and Twelfth Doctor.
“Will they ask? I doubt it. But I don’t know. I mean, I’m very, very lucky to have worked with two Doctors. Two brilliant, brilliant actors. So if not, I will count myself blessed to have been asked back; to have played him these two times. That’s wonderful. And we shall see. Who knows? Yeah, never say never. That’s very true.”
Simm's iteration of the Master seems to have been firmly wrapped up. Indeed, the season 10 finale ingeniously filled in some long unexplained gaps between how the Master got from the Simm iteration to Gomez's flamboyant Time Lady. But as Simm acknowledges, the usual rules of storytelling don't always apply to a show featuring a time machine, so don't be surprised if his Master returns to menace a future Doctor or two.
