Analyze this: Christa Miller follows her own path as Liz in Season 3 of Apple TV’s ‘Shrinking’

Over the course of her career, Christa Miller has shared the set with many actors.

Yet, when the opportunity to join the cast of Apple TV’s “Shrinking” came to her, she jumped at the chance.

“The best part about being part of this show is my castmates,” Miller says. “I get to work with all these hugely talented people and the talented guest stars. Everyone takes it all so seriously.”

The third season of the acclaimed series is currently airing, with a new episode each Wednesday on Apple TV through April 8. Before its premiere on Jan. 28, Apple TV announced the series was renewed for Season 4.

“Shrinking” follows a grieving therapist, Jimmy Laird, played by Jason Segel, who starts to break the rules and tell his clients exactly what he thinks. He finds himself making tumultuous changes to people’s lives, including his own.

Along with Miller and Segel, the series stars Harrison Ford, Jessica Williams, Luke Tennie, Michael Urie, Lukita Maxwell and Ted McGinley.

The third season also features guest stars Brett Goldstein, Damon Wayans Jr., Wendie Malick, Cobie Smulders, Jeff Daniels, Michael J. Fox, Candice Bergen, Sherry Cola and Isabella Gomez.

Miller portrays Liz on the series, the witty, supportive and sometimes overbearing next-door neighbor and friend to Laird and his daughter. Miller also serves as the show’s music supervisor.

“Liz is a different person than me,” Miller says. “She is the opposite of me and she’s taught me a bunch of things. She’s not afraid to be embarrassed. She’s not afraid to try something and fail. I root for her. She strives to be better and feel better, which is important.”

Miller says her real-life psychiatrist is the basis for Ford’s character.

“I push for mental health wellness,” she says. “This is why it’s important to be part of a show that speaks about this in such a great way. It’s not forced.”

In Season 2, Liz’s arc focused on her struggle to find purpose outside of being a neighbor and mother figure. Her frustrating attempts to fix others — especially her son Connor — backfires and she steps back and begins to follow her own path.

“Liz still hasn’t solved her problems in Season 3,” Miller admits. “She’s making some progress and as the season unwinds, audiences will experience her journey.”

Being a part of the series, Miller takes many of the lessons she’s learned on set, and from her castmates, and applies them to daily life.

“I try to be there for my friends,” she says. “Instead of saying what can I do, I will offer help. If someone is going through a bad time, I will show up with food. Anytime that you can be accountable and show up, it’s great. It’s something Liz would do and it’s something I’ve been putting into my life.”

Miller also credits her patience, which helped her get the part.

“When I read the script really early in the process, I knew I had to do the show,” Miller says. “This was after the writer’s strike, and productions were just starting again. It all seemed to work out, and we’re able to be part of this amazing series.”
