Alex Kingston has commented about her future on Doctor Who in the new issue of the Radio Times. Her character, River Song, is already confirmed to appear in the finale of Series 7.
She said: "I’m so attached to that character. I never expected her to grow and develop in the way she has. You never know whether she’s going to be hard-ass or good. As long as Steven Moffat has storylines that include her, I will always say yes,”
Series 8 begins filming in September as confirmed in our article yesterday.
