And that's actually the only comment on Doctor Who in this Guardian interview with the actress who plays River Song. Here's the relevant snippet: "Over the past five years, Kingston has reached a new audience with Doctor Who, and reacts with playful, cagey laughter when asked if she'd like a woman Doctor to replace the outgoing Matt Smith. "Spoilers!" she laughs, repeating one of her character's buzzwords. "I can't say." Given that River, a time-travelling archaeologist, has been romantically involved with the Doctor, such casting could be especially progressive, creating a gay relationship for the chief protagonist. "Well, you know, I wouldn't put it past Steven," she says, referring to the show's lead writer and executive producer, Steven Moffat. She agrees this would be brilliant. "Certainly, River has always talked about 'the special one' when referring to the Doctor."

So not the most informative quote ever, but at least we know now that if Moffat were to try such a storyline, Kingston would be fine with playing the part. Of course doing a lesbian Doctor relationship would require there to be a female Doctor, and we won't hear confirmation of the next actor until August at the earliest, as per the Radio Times. The rest of the interview is worth a look while you're at it; Kingston is starring in the Manchester International Festival production of Macbeth as Lady Macbeth (3 July to 20 July, and the last day you can watch it at some UK cinemas). Also there's some quite good musing on race and gender issues in the US v. the UK. Enjoy.
