But who is this McCord character? Check out this interview with Edelstein for some clues.
What can you say about your “Castle” role?
Lisa Edelstein: I play a brilliant woman who serves as a mentor to Beckett.
I can’t really say what we’re doing together — which makes it very challenging. I would say that McCord really challenges Beckett to push what it is that she wants and expects out of a career. That’s definitely going to challenge Beckett in whole new ways.
How would you describe going to work on the show?
Lisa Edelstein: Fantastic! What a fantastic group of people, truly. They were so welcoming and so warm. Stana was an absolute doll. You know, I came in and had to really bond with her, because we had most of our stuff together and we really needed to be like we had a great relationship. It was easy with Stana, because she was so excited and welcoming.
After the first three episodes of Season 6, is there any chance that your character might return to “Castle”?
Lisa Edelstein: Andrew [Marlowe] has been open for me to come back later on, but it really depends on my availability. I’ve signed on for my next project, so that limits the amount of time.
How does work on a police procedural compare to a medical procedural like “House”?
Lisa Edelstein: In terms of my part, Cuddy was not on the team on “House.” I was separate from the actual procedural nature of the show. I didn’t have to do a lot of that stuff. What I did have to do a lot of was say, “House! No!” And now I get to say things like “Federal agent! Drop your gun!”
I’d like to limit the amount of time I ever have to say that again — in either case. I think Stana has done a truly remarkable job through the years of saying “Drop your weapon” and still making it sound like something a human being would say. So I was very impressed with that.
Can you tell us about your new show?
Lisa Edelstein: It’s a pilot for Bravo called “The Girlfriend’s Guide to Divorce,” from Marti Noxon. And I am so excited about this part. It’s super exciting and fun and dramatic and wonderfully exposing the modern-day problems of walking into a life when you’ve spent the first half of it married. It’s great! And I love that the story is about a woman in her 40s. It’s very timely and very smart and very funny.
Was this the sort of role you were looking to play?
Lisa Edelstein: I have really been so picky, because — thankfully — with “House,” I could afford to wait. I’m very grateful for that. I really just wanted to do a project that I was fully engaged in, that I loved being in. Because it’s very hard to have a career like mine — it’s very hard to be in this business! And so, my theory about it is that if you have to take risks just to succeed, it’s that much more important that what your success looks like is something you’re happy with. This project really stands up to all my prerequisites. I’m so excited!
“Castle” Season 6 premieres Monday, Sept. 23 at 10 p.m. on ABC.
