Ncuti Gatwa’s 15th Doctor takes his new companion Ruby Sunday, played by Millie Gibson, on a time travel adventure in the teaser of the latest instalment of the British sci-fi show Doctor Who.

Reprising his role as the iconic doctor from the Christmas special episode aired on December 25, Sex Education star Gatwa will also headline the latest season, to be referred to as Season 1, of the long-running BBC sitcom, confirmed showrunner Russel T. Davies.

Dropped by BBC on Tuesday, the 42-second-long teaser shows Gatwa’s Doctor and his companion, Ruby, travel to different time periods, including the Regency era and the swinging 1960s.

The Doctor also tells Ruby about otherworldly dangers and fights off vicious space monsters in the teaser. “I’d love it if you came with me,” says his voiceover at the end, hinting at the Doctor’s loneliness as he continues to traverse the universe through time.

Yasmin Finney and Bonnie Langford will be reprising their roles as Rose Noble and Mel Bush, respectively, in the upcoming season, while Jinkx Monsoon will feature as a formidable enemy.

Doctor Who follows the adventures of a 2000-year-old Time Lord, known simply as the Doctor, as he traverses time and space with his companions in TARDIS, a spaceship that looks like a British police box. It is the world’s longest running television series, which was launched by the BBC in 1963.

Produced by Bad Wolf and BBC Studios, the popular sci-fi franchise celebrated its 60th anniversary with a three-episode special series on Disney+ Hotstar released on November 25.

Doctor Who Season 1 will hit BBC’s iPlayer in 2024. However, the exact date has not been announced yet.
