Coleman had this to say in an interview with Kroq radio in America:
"I think that is the brilliant thing. Bringing in a new character is hard, but Steven has done the best thing and been very clever by creating this mystery."
"Oswin was a guest role originally; I was auditioning for the companion that was already written. But the cogs were turning with Steven and he pieced this story together by having me be Oswin."The actress also spoke about the relationship between the Doctor and Clara:
"We kept it a surprise; I was under lock down in the studio. For real fans it was amazing."
"There is always a frisson between the Doctor and his companion and a certain amount of flirtation and teasing. It is based on friendship, when you go every week saving each other’s lives; it is based on friendship really."
"Also Matt’s Doctor is slightly asexual, any kind of flirtation – he won’t get it. It is a little bit clumsy. He wouldn’t realise he was on a date if he was on one."Coleman has no regrets in taking on the role of Clara, despite the show's increasing popularity:
"You don’t want to take a job on and a job people have invested in so much unless you feel you are up to the job."Clara returns to the screen in The Rings of Akhaten, which airs this Saturday in the UK.
"You have first day nerves but as soon as you open a Steven Moffat script, all that goes out the window. You just can’t wait to do it."
"It is brilliant and so limitless what you can do on this series so every episode is so different and it is just exciting. The stuff we get to do day-to-day is not like any other job."
