Ncuti Gatwa's Doctor Who Finds Companion in Millie Gibson

The 15th Doctor has found his companion. 

The BBC announced today that 18-year-old Millie Gibson (Coronation Street) would play the role of Ruby Sunday, companion to Ncuti Gatwa's Doctor. 

"Whilst still being in total disbelief, I am beyond honoured to be cast as the Doctor’s companion. It is a gift of a role, and a dream come true, and I will do everything to try and fill the boots the fellow companions have travelled in before me," said Gibson in a statement. "And what better way to do that than being by the fabulous Ncuti Gatwa’s side, I just can’t wait to get started."

"Millie just is the companion. She is full of talent, strength, she has a cheeky sparkle in her eye and is sharp as a razor. From the moment she walked into the room she captured all of our attention with her effervescence and then solidified that attention with the sheer torque of her talent," said Gatwa. "This adventure is going to be so wild and so fun, I cannot WAIT to sail the universe with Millie!"

David Tennant is currently playing the Fourteenth Doctor, and will be followed by previously announced Sex Education breakout Gatwa as Fifteen in late 2023. 

Also starting in late 2023, the iconic series will debut new episodes starring Gatwa in the title role on the BBC in the UK and Ireland, and Disney+ everywhere else. In the United States, Doctor Who had aired on BBC America in recent years. 

Doctor Who is currently available to stream on HBO Max.
