Doctor Who star Jodie Whittaker is set to make her final appearance as the Time Lord.
She has led the show since 2017, and will end her time on the sci-fi series with a feature-length centenary special on 23 October.
In an episode titled The Power Of The Doctor, Whittaker will take on some of her deadliest enemies – including The Master, Daleks and Cybermen.
The actress announced she would be leaving the show in July of last year.
The episode will mark the first time all three of the Doctor’s main enemies have featured in a single storyline since 2005.
Fans will see her try to work out who is attacking a bullet train in a distant galaxy and why 21st century seismologists are going missing from Earth.
Janet Fielding will reprise her role as Tegan Jovanka – companion to the fourth and fifth Doctors,
Sophie Aldred – who starred as Ace, companion to the seventh Time Lord – will also be making a comeback.
