Russell T. Davies is thrilled to be back at work on Doctor Who

The writer/producer has been credited with reviving the BBC series back in 2005 during his tenure as head writer and producer but exited in 2009 to work on other projects before announcing he would return as showrunner to look after the 2023 run.

Speaking during an appearance on 'The Graham Norton Show', Russell admitted he's thrilled to be back working on his beloved series, saying: "I am loving it, loving it so much. We’ve three specials and then a brand-new doctor, who is amazing."

'Doctor Who' returns this year with Ncuti Gatwa in the lead role.

Russell's latest project is a new three-part series for ITVX called 'Nolly' which stars Helena Bonham Carter as 'Crossroads' actress Noele Gordon.

During his chat with Graham, Russell admitted he was a huge fan of the soap - which originally ran from 1964 until 1988 - and was thrilled to get a chance to write a script for the show shortly before it was cancelled.

He said: "The first thing I ever wrote was a script for 'Crossroads'. I sent it off and they invited me to Birmingham. I was so excited to be there because I loved it so much, but I could see the fear in their eyes when they realised, I was a super fan. I went away and wrote a proper script and sent it off. Five days later the show was axed. I waited 40 years and finally got to write it so got there in the end!"

'The Graham Norton Show' airs on BBC One on Friday January 20 at 10.40pm. It is also available on BBC iPlayer.
