What drew you to the character of Joy on And Just Like That…?

It was just so flattering to be approached about it. I was now so into the show, and I just thought Joy sounded cool. I thought, I really like the BBC, because, you know, if you’re English and you’re an actor, you’re always sort of hoping to be on the list to be in things that the BBC makes. They make really good television, and and they have no commercials, and there’s just something wonderful about the old tradition of having a BBC that makes brilliant things. I liked that Joy was a BBC producer, and I loved Miranda’s character. I didn’t get told very much in the beginning, I just knew that I was a producer and that I would meet Miranda outside the UN, but I was drawn to the potential of it and I liked what I read. I just thought Joy sounded interesting.

What was it like working with Cynthia Nixon?

She is a dream. I really admire her. She’s incredibly good at acting, obviously, so she’s really fun to act with, and she’s so bright and curious and interested and gracious; she’s really wonderful. Being on And Just Like That… in the third season sort of feels like you’re joining a new school and you don’t want to try too hard with all the big girls. You sort of want to play it a bit cool. I remember being at the read-through and just being like, Oh my gosh, look at them all. Wow. Everybody is so friendly, though, and the thing that really moves me is that they still have such passion and excitement for the work, including Michael Patrick King and John Melfi. There’s such a feeling of excitement and joy and happiness to be doing it, and I felt really lucky. Cynthia is just a really, really nice person who I really like and admire, and it’s lovely to play her girlfriend.

Do your kids watch you on the show?

My son doesn’t yet, but he will. My daughter does, and what’s so cool is that my best friend Emily [Mortimer], her daughter May, who’s 15, has been watching the whole series. It feels amazing that there’s this whole new generation of young people watching it.
