The Copenhagen Test, which aired on Peacock, is a fast-paced spy thriller, that keeps you guessing at every turn. Kathleen Chalfant plays the character of St. George, a mystery woman who is the head of the secret organization known as The Orphanage. You may also know Kathleen from her illustrious career playing characters such as Margaret Butler on The Affair, or guest arcs on Madame Secretary and House of Cards.

SciFi Vision recently had a chance to sit down with Chalfant to talk about her work on the series.

Read the transcript below.

SCIFI VISION:   So, we know St. George is the founder of the orphanage, and she knows everything. How much did you Kathleen know about where the story was going, or did you learn like the audience.

KATHLEEN CHALFANT:   We learned like the audience…I knew the outlines. They didn't give us the last episode until sort of a week before we were shooting. We shot in blocks. So, we shot two episodes at a time, so seven and eight we didn't get until we were around the time to shoot seven and eight.

SCIFI VISION:   If the show is picked up for a second season, has the creative team discussed with you the direction they'd like to see St. George go in? Personally, I'd like to see more of St. George and Kate's history.

KATHLEEN CHALFANT:   Thank you. Yes, I think we will find out more about St. George and Kate. Thomas, who's the original creator knows, I think, 10 years. 50 years of backstory and 10 years into the future, so he knows what's going to happen.

SCIFI VISION:   What was your audition process like for this?

KATHLEEN CHALFANT:   I think I just had an interview with them, which was very flattering. You know, when you're really old - I turned 81 yesterday, so people are kind and don't make you audition quite so much, but also there's lots of evidence of whatever it is you can do.

So, I had an interview with most of the creative team for the first block. And I was working. I forgot, I don't know, I don't remember where I was, but I think that the interview happened when I was backstage.

SCIFI VISION:   What kind of roles do you prefer to play? Like, you played the snarky grandma in The Affair, and now, you're like the head of a secret spy organization. What's the thing you like the most?

KATHLEEN CHALFANT:   Those are a lot more fun than playing people, you know, tied to their beds or something. It’s an interesting idea. Now, in popular culture, all the spy agencies in the world are run by women of a certain age, I think it's very cool. It might be nice if we tried it in real life things might work out better. So, those parts are wonderful, because they're mysterious, and people like Margaret on The Affair are great, because they are the people who say the things you wouldn't dare to say, and that makes it fun. You know, it's wonderful to play a character where people say, “I can't believe she said that.”

SCIFI VISION:   If you could play any other character in the Copenhagen Test, who would it have been and why?

KATHLEEN CHALFANT:   Well, if I were any age, I would like to - it'd be great if I were a kid. It would be wonderful to play Sinclair's part. Since I, you know, because the idea that one of the protagonists of a spy series is a playwright is a wonderful thing for somebody who comes from the theater. It's a wonderful idea. The idea that it's the same skill set, being a spy, in that particular way writing scenarios for people and figuring out their psychology is the same skill set as playwrights skill set.

SCIFI VISION:   Do you have any other projects coming up soon?

KATHLEEN CHALFANT:   I do. I'm in rehearsal right now for a play called The Dinosaurs at a theater called Playwrights Horizons in New York. And I have two movies, the one in the late spring, and one in the late summer early fall. The first one is by a filmmaker who's mostly done documentaries until now named Nela Wagman, and the second one is written and directed by Sarah Friedland who was the writer and director of this in this movie that I did with her called Familiar Touch, and we won a bunch of prizes at Venice and are nominated for an independent spirit award. So, this will be Sarah's second feature film, which is very exciting, and I get to be in that one too.

SCIFI VISION:   Have you ever thought about switching gears from acting to directing or writing or anything?

KATHLEEN CHALFANT:   No, I think people should, I mean, at least I think I should do the thing that I'm best at and I know. I don't think the world needs either second rate writer or an adequate director. So, I decided I should stick to stick to what I'm doing. I've helped start a lot of theaters, mostly because I can type, and that's a skill set that I seem to have but that doesn't interest me to use. So, I've just been sticking to acting.

SCIFI VISION:   What would a dream role be for you?

KATHLEEN CHALFANT:   I think there are ways in which St. George is a dream role. What to say? I've been very, very lucky in my career. So, I've fallen into a number of dream roles. I was in the original company of Angels in America and got to play all sorts of people from the Mormon mother to the ancient rabbi to Ethel Rosenberg in that play, and then I was in the play Wit. And then this movie Familiar Touch, and I just seem to fall into things. So, I think I'm going to stick to betting on my luck. Whatever comes along it's been okay; it's worked pretty well so far.
