The 40-year-old actress - who will soon make her final outing as the iconic character - has loved her time in the role, admitting it's made her feel "energised".

Jodie - who became the first female to land the role in 2017 - told the Daily Mirror newspaper: "Before I played the Doctor I spent quite a lot of time playing people who lost children, people whose husband had been disabled - you don’t realise how much that emotional trauma leaves you on the edge of upset when you’ve been doing it for 12-hour days.

"With 'Doctor Who', there was heartbreak, there was fear and there was loss, but my overriding emotion was excitement. That really fed into my evening and my weekend and my year.

"I feel like it’s knocked 15 years off me because I’ve been so energised."

Earlier this year, Ncuti Gatwa was announced as the new star of 'Doctor Who'.

The 30-year-old actor - who is best-known for starring in the Netflix series 'Sex Education' - was confirmed as Jodie's replacement, and he's "deeply honoured" to have been handed the opportunity.

Looking forward to his new role, Ncuti - who will become the first black actor to play the iconic character full-time - said: "There aren’t quite the words to describe how I’m feeling. A mix of deeply honoured, beyond excited and of course a little bit scared.

"This role and show means so much to so many around the world, including myself, and each one of my incredibly talented predecessors has handled that unique responsibility and privilege with the utmost care. I will endeavour my utmost to do the same."
