New Doctor Who companion revealed – watch

Pearl Mackie plays the Doctor's new sidekick, Bill

The new companion for Peter Capaldi’s Doctor Who, Bill, has been revealed.

Bill is played by Pearl Mackie, a relative newcomer whose past experience includes 2013 independent film Svengali and BBC One’s Doctors.

As reported by Radio Times, she is an actor and singer from Brixton, south London, currently starring in the National Theatre’s production of The Curious Incident of the Dog in the Night-Time.

In the clip introducing the new character, Bill annoys the Doctor by asking him questions about the deadly Dalek chasing the pair, including why it has a sucker and why it says ‘exterminate’.

Mackie will make her Doctor Who debut in the tenth series of the popular sci-fi show, which is set to air in early 2017, following a Christmas special later this year.

The position of the Doctor’s companion has been filled by Billie Piper, Karen Gillan and Jenna Coleman in recent years with the latter’s Clara Oswald departing in the most recent series and opening up the vacancy alongside Capaldi.

Speaking to Brazilian website Omelete last month, Capaldi said that he was “very excited” about the new companion. “Obviously I know who that is and we’ve been doing a bit of work together already and it’s very exciting,” he said. “Because it’s a very different sort of take on it.”

Explaining how this sidekick will be different, Capaldi continued: “Clara had prior knowledge of the Doctor. It was conceived as a human connected to your timeline, and so had access to the cosmic nature of the Doctor. She understood a little about how he was. And as she was already with Matt [Smith], she knew the Daleks and the TARDIS. Now we have someone who knows very little about the Doctor.”

The ninth series of Doctor Who aired in 2015, having being revived by the BBC in 2005. Speaking in November 2015 showrunner Steven Moffat said that at least five more series are already being planned.
