Fans of the long running BBC show Doctor Who will be pleased to hear that the eighth series of the show is already being planned by current show runner Steven Moffat, meaning the show will not be changing hands any time soon.
The current Doctor, Matt Smith, has been confirmed to return for at least one more season for some time now, but it has not been stated that he will be there for the entire season. In an interview with Entertainment Weekly, Smith stated that he believed that no one can play the Doctor for seven years like Tom Baker did because "it would age you too savagely."Since the show was picked back up in 2005, the longest an actor has remained as The Doctor is four years. This was done by David Tennant who was The Doctor for three seasons and many specials.
In an interview at The Gallifrey One 2013 Convention in Los Angeles, Moffat talked about the possible villans that may come back in the next series. He talked about writer Mark Gatiss' idea for bringing back the ice warriors, which he has apparently been pitching for a while now. Moffat also mentioned that bringing back The Doctor's arch rival, The Master, is not completely off the table.
The rest of series seven will start back at the end of March with Jenna-Louise Coleman as the new companion. There will be eight new episodes to finish off this series.
