She’s earned the role of Peter Capaldi’s right-hand woman in series 10 of Doctor Who.

And Pearl Mackie, 29, was pictured filmed scenes for the popular sci-fi drama in woodland in Cardiff, on Friday.

Illuminated by large lamps, Pearl’s character appeared concerned as she gazed into the distance.

The shoulder and collar of her red sweater were covered in mud, indicating she’d been in some sort of struggle.

One of her co-stars was dressed as a knight in chainmail and heavy-duty armour, suggesting she had returned to a bygone era.

The Doctor’s assistant looked lost and alone as she made her way through the undergrowth, possibly being stalked by a dangerous enemy.

In between takes, Pearl wrapped up in a coat and chatted with crew members.

Pearl was cast in April to replace Jenna Coleman, who quit the sci-fi series after its ninth outing, when the show returns in spring 2017.

She was first seen filming for the show in June. Pictured on set at a late-night shoot at Cardiff University, she showed off her svelte figure in a striped vest top and jeans.

The theatre actress – best known for her role in The Curious Incident of the Dog in the Night Time – was announced as the Doctor’s new sidekick during the FA Cup semi-final match, with a special teaser trailer showing her and the Time Lord facing off against a Dalek.

She certainly has a fan in her co-star Peter, who said: ‘It is a genuine delight to welcome Pearl Mackie to Doctor Who’.

‘A fine, fine actress with a wonderful zest and charm, she’s a refreshing addition to the TARDIS and will bring a universe of exciting new possibilities to The Doctor’s adventures.’

Doctor Who series 10 will air next Spring, with filming expected to finish on March 31.
