Speaking to us at the BFI Southbank (above), Moffat went on to discuss the interplay between new companion Bill and the Doctor, which audiences will see for the first time this Saturday evening.
“The way he plays off Pearl is different,” Moffat told us. “Because there was a sort of commonality between him and [former companion] Clara that meant he could behave quite… not brutally, but sometimes without due care, and the compassion would come out more occasionally.
“He doesn’t quite know what to make of Bill at the beginning, so he’s more careful. And he’s very much more the grandfather, the tutor, the instructor. Who as it turns out, and she quickly learns, is completely barking mad.
“I think [audiences are] gonna love her,” he added. “I hope they’re gonna love her – we love her. The early indicators in terms of people looking at the show have been very, very good indeed.
“It’s a wonderful, spirited, engaging performance. And she is quite a different tone of voice for us. I think genuinely quite a different tone of voice for us. But you know, hey… I’ve given up trying to predict.”
Based on what we’ve seen, we’d say
audiences are in for a treat with Bill – even if we are still pretty excited about the next Doctor as well. We contain multitudes.
Doctor Who returns to BBC1 on Saturday 15th April at 7:20pm
