Doctor Who just announced the new companion who will join the Doctor in the next series, and it's Ruby Sunday, to be played by Millie Gibson. Doctor Who returns in 2023 for the show's 60th anniversary, with David Tennant and Catherine Tate returning for three specials. Russell T. Davies, who wrote the show from 2005-2010, is also set to return. Once the familiar faces leave the TARDIS once again, the new season of Doctor Who is where the unfamiliar future begins.

Sex Education's Ncuti Gatwa has already been announced to be taking over full-time from Jodie Whittaker as the Doctor. Russell T. Davies is not only returning for the 60th anniversary but to write for season 14 and beyond. And now fans of Doctor Who know the identity of the full TARDIS team, as alongside Gatwa, Millie Gibson has been cast as the new companion, Ruby Sunday. Doctor Who was brought back to screens for the new season 1 in 2005 with Christopher Eccleston and companion Billie Piper. Funnily enough, Gibson will join the show for season 14, and she hadn't even been born yet when Piper was announced as Rose Tyler. Such is the longevity of Doctor Who.

What Millie Gibson Has Been In Before Doctor Who

Millie Gibson Coronation Street

Millie Gibson has been in a number of projects before Doctor Who. She started out on CBBC show Jamie Johnson, which she starred in for two seasons. The show followed Jamie Johnson as he navigated high school and being a talented football player. Gibson played Indira, who was initially introduced as a stereotypically vain, snobby popular girl, but she evolved as the series went on. Gibson then made an appearance in one episode of BBC show Love, Lies and Records, and had a main role in the three-part drama Butterfly as Lily Duffy.

Her most notable role was in the British soap opera Coronation Street. In that, Millie Gibson played Kelly Neelan from 2019-2022. After having been on the show for four years, she left Coronation Street, and now it's clear why. She's left the cobbled streets of Corrie to travel in time and space on Doctor Who.

What Millie Gibson's Previous Roles Reveal About Ruby

Millie Gibson's previous work should set her up well for life on Doctor Who. As the show is a family show, and started life in the '60s as a children's show, Gibson's work as a child actor in a children's show should have given her great experience to play Ruby. She will have to be relatable for all the new set of younger fans who will come to the show for the new era, which should be sizable since Disney+ will now be the home of Doctor Who outside the UK.

Just before she left Coronation Street this year, Gibson won an award at the British Soap Awards for Best Young Actor. This is great news for fans who are unfamiliar with her work, showing that she is a talented actor and is more than capable of stepping into the new TARDIS. While Ncuti Gatwa is a bigger name than Millie Gibson, everything points to strong new Doctor Who stories and an awful lot of running for Ruby Sunday and the new Doctor.
