The Huddersfield actress was appearing on The Late Show with Stephen Colbert on Wednesday evening in the USA when the side-splitting subtitle gaff happened.
A still from the show was shared on social media network Twitter by user @dotski_w, showing the word Huddersfield had been spelt 'Hoodezfield'' on the show.
The full line read: "I'm from Hoodezfield, in West Yorkshire."
The internet reacted in a typically comical fashion.
@pbhellawell wrote: "Ha! I hereby declare the town Hoodezfield from henceforth!"
@ClausVistesen said: "The Z is a nice touch; bold, but nice."
@Lloyd_Butler_ found the wrror amusing, writing: "No way. NO WAY! HOODEZFIELD?! AAAAHAHAHAHAHAHAHA Serious but. Huddersfield should consider changing its name to this."
@Thessilian said: "OH MY GOD I'M LAUGHING SO HARD i mean legit that'll be what she sounds like."
There’s an all-new supporting cast, with Bradley Walsh, Mandip Gill and Tosin Cole playing The Doctor’s companions.
It’s moving from Saturday nights to a brand new slot on Sunday evenings, while new showrunner Chris Chibnall, of Broadchurch fame (which Whittaker also memorably starred in) – promises it’s bigger and bolder than ever before.
