The 58-year-old actor is playing companion Graham in alongside younger stars Mandip Gill, 30, and Tosin Cole, 26, in the upcoming series, and he has suggested people their age will be reminded of their grandparents.

Speaking at the BBC show's launch in Sheffield this week, he said: "Hopefully younger viewers will look at my character and some of the things I say and do and think, 'Oh my dad would say that. Oh my grandad would say that', so that's me.

"I'm the elder statesman keeping that sort of side of it together. You've gotta keep the grey pound happy."

While 'The Chase' star is excited for the role, he joked his age means he can't jump around as much as new Time Lord Jodie Whittaker, 36, does.

He teased to Metro.co.uk: "I walk up stairs once! It's only once and it was two steps. I had to have a stand in to walk up the steps. I came down, I couldn't walk up."

His appearance alongside his co-stars on the red carpet comes after Bradley urged Whovians to tune in to see the beginning of the new era when it hits the small screen on October 7.

He previously said: "If there are any 'Doctor Who' fans out there, Jodie is magnificent.

"It was unbelievable. It is really big stuff and they have gone for it."

Meanwhile, the star recently revealed how new showrunner Chris Chibnall - who he worked with on 'Law & Order UK' has met with him and executive producer Matt Strevens to pitch "a drama that would shoot in Wales for nine months".

He recalled: "They said, 'It'll be a fantastic journey and will hopefully change the way everyone perceives a certain show'. I had no idea it was 'Doctor Who', I had no idea!"
