The 31-year-old actor - who shot to stardom after he appeared in Netflix's romance drama 'Sex Education' - picked up the Sonic Screwdriver and took over the TARDIS in the latest 'Doctor Who' 60th Anniversary special, 'The Giggle', as he joined forces with David Tennant's Doctor, but he's insisted he doesn't know how long he will have the role for.

During an interview with Radio Times magazine, the actor was asked whether his time on the BBC show would go beyond the second season and said: "No idea, no plan. I just know that I’m loving it and my love for it is growing."

Despite his uncertain future on the BBC programme, Ncuti emphasised that he had settled into the role.

He added: "It feels so much fun now. I’ve relaxed and [the Doctor] seems to have sunk down a little bit deeper, from my chest into my gut."

Although he is loving the part, Ncuti revealed it hasn't always been smooth sailing.

The actor recalled a moment where he was pulled aside by showrunner Russell T. Davies and scolded after he swore on set whilst wearing his 'Doctor Who' costume.

He said: "The only time I’ve ever gotten in trouble for anything was when I swore [while wearing] a Doctor Who costume.

"I got called into Russell’s office. Woo! And he let me know that that’s not acceptable. He said, ‘Do what you want when you’re out of costume, but when you’re in costume, do not let us catch you swearing.'

"I was like, 'fair enough'. And I guess that was a lesson. For the last four years, I’ve been co-leading an X-rated show, and so I’m on a constant journey of learning what it is to be a PG role model and the lead of a family show.”
