On joining the cast in her first major television role, said:

I'm incredibly excited to be joining the Doctor Who family. It's such an extraordinary British institution, I couldn't be prouder to call the TARDIS my home!

Peter Capaldi is such a brilliant actor, and his Doctor is such a wacky and wonderful character, I can't wait to see what adventures are in store for him and Bill throughout time and space. Reading the script at the audition I thought Bill was wicked. Fantastically written, cool, strong, sharp, a little bit vulnerable with a bit of geekiness thrown in - I can't wait to bring her to life, and to see how she develops through the series.

I always loved stage combat at drama school so I can't wait to get on set and kick some evil monsters into the next dimension!

Shooting the trailer was absolutely mental, there were pyro technics and smoke and I met my first Dalek! I'm not sure it will ever become ‘the norm’ seeing crazy monsters on set, but I cannot wait to meet some more! The weirder the better, bring it on!

Peter Capaldi said:

It is a genuine delight to welcome to Doctor Who. A fine, fine actress with a wonderful zest and charm, she’s a refreshing addition to the TARDIS and will bring a universe of exciting new possibilities to The Doctor’s adventures.
