Jenna-Louise Coleman has revealed that Saturday’s big final of Doctor Who “couldn’t be much bigger”.

In The Name of the Doctor there will be lots of surprises as Clara’s “impossible” identity is revealed along with the Doctor’s “greatest secret”, and who knows what else? In an interview with What’s On TV, the actress teased that the stakes have never been higher. “It is a huge episode,” she said. “It leads nicely to the amazing 50th anniversary this November.”

She reaffirmed that the events of the finale will alter “the direction of the show forever”, promising: “What happens to both Clara and the Doctor really bonds them together. It is transformational and revelatory.” And their relationship will feel “a lot freer” after it is all out in the open. “What’s been interesting filming the 50th is that all of that’s been lifted away,” Jenna explained. “It is all about those two and spending time together. It’s a nice change and it’ll be interesting to see where it goes with Clara and the Doctor from here.”
