ussell T Davies says a "Doctor Who" return would be a step backwards.
It has been over 14 years since the 55-year-old screenwriter was first at the helm of the BBC science fiction favourite - where he spent five years as showrunner - and he has insisted he has no plans to make a comeback because he'd rather look ahead in his career.
Speaking to the RadioTimes.com, he explained: "It'll be like coming back to a job I did 10 years ago, wouldn't it? Who would do that?"
It echoes the sentiment he has voiced in the past, when he penned the novelisation of the "Rose" episode.
He said at the time: "Really, think about it. Go back to the job you had 13 years ago. Or go back to your old school. Walk in, say hello, take your old seat. And start giving instructions! Watch everyone's faces. Shortly before they call the police.
"Move on! And besides. Why look back? The future is golden."
Now, Davies is focused on his upcoming new show "Years and Years", which is set in the future and moves forward "another year more or less" with each episode.
He added: "It jumps five years ahead in the first episode and then every week it goes forward another year more or less. But in the end, it will be set 15 years in the future."
Emma Thompson has been cast as Prime Minister Vivienne Rook - described as a mix between the former Mayor of London Boris Johnson and leader of the Brexit Party Nigel Farage - in the show, and Davies recently revealed he's delighted to have her on board.
He said: "Emma Thompson, you don't just see her on television, and to cast her was a dream come true."
