Buffy creator reckons it would be “daunting” to write for the BBC series.

Joss Whedon writing an episode of Doctor Who sounds like a match made in Heaven – but he’s got a few ground rules.

Speaking at San Diego Comic-Con’s Nerd HQ, the Buffy creator was asked if he’d consider writing for the BBC series.

“Check back with me when the Doctor is a she…” he hinted, “…or Idris Elba!”

Whedon’s the latest big name to throw his support behind the notion of a female Doctor – with ex-Who star Matt Smith recently suggesting that “a lady Doctor could be close“.

Further on the topic of writing for Doctor Who, Whedon said it would be “very daunting” to “following in the footsteps of Moffat and the guys.”

“I’m not sure [if I’d do it] – and here’s why,” he said. “I’d have to do a lot of research – like, what, watch 40 years of television? I mean, I’ve seen some of it, but let’s get real.”

Joss, get binge-watching. Steven Moffat (or Chris Chibnall?), get him on the phone.

We need this to happen.

Doctor Who will return to BBC One in December for a Christmas special, with a full series to follow in 2017.
