Doctor Who‘s executive producer has revealed that fans will learn more about Missy’s history with the Doctor in the new season.

Missy will return in Season 9’s two-part opener, ‘The Magician’s Apprentice’ and ‘The Witch’s Familiar’.

Speaking to SFX in the magazine’s new issue (on sale now), Brian Minchin teased: “Missy is brilliant, and having seen her in the finale we just couldn’t wait to work with Michelle again. Steven [Moffat] had the perfect story.”

He added: “It’s not going to be Missy as you expect her to be. Steven likes to surprise everyone and he’s going to do that with this opening. Missy has an awful lot of sides to her and we’re going to see some new ones in this series. We also learn a bit more about her relationship with the Doctor…”

Steven Moffat hinted earlier this year that “there are certainly surprises” when Missy returns.

It was revealed yesterday that the new season will apparently consist of 12 episodes, followed by a Christmas special.

Season 9 began filming in Cardiff in January and will air on BBC One this autumn.
