And Whittaker, who was born in Skelmanthorpe, near Huddersfield, said that not having to worry about dialect helped her concentrate on other aspects of the role.
The BBC has already confirmed South Yorkshire's prominent role in new series 11, which features the line: "We don't get aliens in Sheffield". Another person who has seen a preview of the episode wrote: "New #DoctorWho is sensational".
This is unmissable TV, an edge-of-the-seat adventure, though some younger viewers may be left hiding behind the sofa when the first super scary new monster reveals itself - just as fans did more than 50-years ago when the Daleks first landed.
"I came into the audition process and I said... There's fun, there's monsters, there's action-adventure, there are characters and there's an wonderful new Doctor".
A trailer for the show pictured Whittaker standing against the Sheffield skyline and Bradley Walsh was pictured reading a fictitious Sheffield newspaper in a fish and chip shop in a publicity still for the show.
"What we've tried to do is just show the range of what Doctor Who can do visually, emotionally, geographically, in time and space, the whole range of everything". When a mysterious woman, unable to remember her own name, falls from the night sky, can they believe a word she says?
"And it's fantastic. I'm just thrilled with it, I really am".
Building to the groundbreaking debut of Jodie Whittaker's Doctor on Sunday October 7, BBC AMERICA will travel through time to bring back ALL of Doctor Who's modern era.
