Doctor Who star Peter Capaldi has been hinting about Nardole’s involvement in the new season.

Matt Lucas first appeared as Nardole in 2015’s Christmas special and has been a regular since last year’s festive episode, ‘The Return of Doctor Mysterio’.

Season 10 began on BBC One last weekend with ‘The Pilot’.

Capaldi revealed: “Matt plays quite a crucial part in the show this season. He’s not there all the time but he is there a lot of the time – I don’t want to give anything away really. He’s very funny – a great presence to have on set and very talented and has a strange alien quality about him with his pale skin and clear eyes.”

Discussing the dynamic between the Doctor, Bill and Nardole in the TARDIS, Matt Lucas himself teased: “As the series goes on, I think Bill and Nardole find they have more in common and challenge the Doctor more. Nardole grows to appreciate Bill and what she brings to the TARDIS. The Doctor has grown weary of Nardole but as the series goes on, I think he comes to appreciate what he has to offer.”

He commented: “As far as Nardole is concerned, the less drama, the better. So when a human comes on board he’s not exactly delighted. He doesn’t look up to humans either. He thinks they’re of little consequence (he’s right). I think Nardole wants to stay focused on the task he’s been given and doesn’t appreciate the distraction for the Doctor that Bill provides.”

Matt Lucas added: “You couldn’t go through a whole series with him being as cartoonish as he was in ‘The Husbands of River Song’. That episode was played for laughs because it was a Christmas Special. We get to learn more about him and why he’s there. He has a purpose.”

Season 10 continues at 7.20pm this Saturday on BBC One with ‘Smile’.
