A top actor called John Simm has spoken for the first time about playing a baddie in the new series of Doctor Who.
The show will be back on our screens on BBC One on 31 March, and John will play a mysterious man called Mr Saxon.
“I play a character called Mr Saxon. I don’t think I’m allowed to tell you what he is, but I’m in the last couple of episodes,” he told Newsround.
And he’s not the only new character. The Doctor’s got a new assistant too – Martha Jones, played by Freema Agyeman.
David Tennant, who plays The Doctor, told Newsround we’ll learn little bits about “the mysterious Mr Saxon” all the way through the series.
“At the very end we’ll learn he’s played by John Simm from Life On Mars and many other things,” he said. “And he’s more than a match for The Doctor in a way that the Doctor never even suspected could be possible.”
He also said he goes on an “emotional rollercoaster” in this series.
The first two episodes were screened at a special premiere-style launch event in London on Wednesday.
Freema told reporters she’d had “loads of fun” filming and that fans had been really warm and welcoming.
She said: “Billie (Piper) did a tremendous job. I know no-one likes change but the nature of the show is change and hopefully fans will be cool with that and give me a chance.”
Fourth series confirmed
And there was some good news for Doctor Who fans at the launch too. Head writer Russell T Davies revealed that there will definitely be a fourth series of the sci-fi show this time next year.
He also promised a “fantastic” climax to the third series.
A special trailer showing selected scenes from the rest of the series was also shown. It featured old monsters like The Daleks, as well as completely new ones.
