Jodie Whittaker felt "grief-ridden" during her final days filming 'Doctor Who'.

The 39-year-old actress has admitted shooting her final scenes as the titular Time Lord in the BBC sci-fi series - a role she first landed in 2017 - was extremely "emotional".

She told Entertainment Weekly: "I've shot my version of regen[eration], and it was singularly the most emotional day on set I think I've ever had. It's a really bizarre feeling, because it's the best time I've ever had on a job, and I made the decision to leave it, so it's a really strange thing to do to yourself. It feels like you're giving yourself stitches — like, 'Why have you done it?' But … it felt right."

And although her last day was "wonderfully celebratory", Jodie felt like she was leaving her "family" behind.

She added: "It was a wonderfully-celebratory-slash-grief-ridden day that I could spend with the family that I'd made. I suppose the best thing about it is that the episodes are still on. So until they're off, I don't have to really get my head around the fact that it's not my part."

Following the New Years Day special titled 'Eve Of The Daleks', which saw the Doctor brought back to life over and over, a second episode called 'Legend of the Sea Devils' will air in spring, followed by the big finale for Jodie's Time Lord in autumn this year.

The three specials follow the six-part limited series 'Doctor Who: Flux'.

And the actress insisted there is a possibility she could return to the long-running show in the future in some form.

She said: "Once you're in ['Doctor Who'] you never want to leave. I suppose it gave me a bit of hope — like, 'Oh, when you do leave, it doesn't necessarily mean you leave forever."

Longtime showrunner Chris Chibnall will be replaced by Russell T Davies - who is set to return at the helm of the programme, 12 years after he stepped away from the job.
