What was your fondest memory of working with Karen? Matt: Oh god, there’s so many. Because for me and Karen, we sort of met, and—did any of you see she tweeted a photo of us at our first camera test, did any of you see that? And I can’t tell you how nervous we were. And we look it, in the photo, we’re like, “oh my god, what’s happening, everyone’s telling us that we’re in Doctor Who, people are meant to like us and everyone loves David and Catherine and please don’t hate us…” And so going on that journey was sort of amazing.
