‘Hell Bent’ is shaping up to be quite an episode.

The ninth series finale of Doctor Who will be more than an hour long.
‘Hell Bent’, airing Saturday, December 5 , has been confirmed to last 65 minutes. The previous episode ‘Heaven Sent’ is also extended, at 55 minutes.
The extra length is just as well, given how epic the plot summary for the finale sounds.

If you didn’t know – SPOILERS – the Doctor (Peter Capaldi) will be returning to his home planet and come face to face with his fellow Time Lords on Gallifrey.”If you took everything from him, betrayed him, trapped him, and broke both his hearts… how far might the Doctor go?” teased the BBC.
Gallifrey was long thought destroyed, but in 2013’s 50th anniversary episode ‘The Day of the Doctor’, it was revealed that the planet had actually been ‘lost’ in another dimension.

Meanwhile, Steven Moffat has revealed that Doctor Who ‘s next companion doesn’t even have a name yet – but told Digital Spy that the new character will fundamentally change the series.Mark Gatiss also recently confirmed that a follow-up to last Saturday’s ‘Sleep No More’ is being considered.

Doctor Who airs Saturdays on BBC One.
