Sadie Stanley, known for her role in Karate Kid: Legends, has joined the lead cast of the upcoming Netflix drama Poser. She will appear as a series regular alongside previously announced stars Daisy Jelley and Annie Murphy. The new series is described as a sexy, emotional thriller that explores a toxic female friendship .
This casting marks Stanley’s latest high-profile project following her recent appearance in the 2025 franchise film. The eight-episode series is created by Lauren Iungerich, the showrunner behind popular series like On My Block and Awkward .
What the Netflix Series Poser Is About
Poser centers on two former best friends who have become estranged. The story follows one friend who gets a chance to live the life she has always wanted. In doing so, she hopes to find answers about why their friendship fell apart years ago. Instead, she finds herself pulled into a psychological game involving revenge, betrayal, and heartbreak. The consequences change their lives and the lives of everyone around them forever.
The show is planned for eight one-hour episodes. It will explore complex relationships under the banner of an emotional thriller .
Sadie Stanley’s Character in the New Drama
In the series, Sadie Stanley will play Emmy. Described as a deeply empathetic and unassuming beauty, Emmy lives under the radar but yearns for more. She covets the life of her long-lost best friend, who now lives down the street from her .
This role represents a shift for Stanley into a more dramatic, psychologically complex character. It differs from her recent part as Mia Lipani, the daughter of a boxer, in the 2025 martial arts film Karate Kid: Legends .
The Creative Team Behind the Upcoming Show
Poser comes from writer and showrunner Lauren Iungerich. The series falls under her overall production deal with Netflix. Iungerich will executive produce the project alongside Jamie Dooner through their production company, Crazy Cat Lady Entertainment .
Iungerich is best known for creating and showrunning the hit Netflix coming-of-age series On My Block. She also created the MTV series Awkward, which helped define teen comedy in the 2010s. Her involvement suggests Poser will offer sharp writing and a deep dive into complicated interpersonal dynamics .

Her recent film work includes the 2025 movie Karate Kid: Legends. In that film, she acted alongside Ralph Macchio and Jackie Chan, playing Mia Lipani, the daughter of a former boxing champion played by Joshua Jackson . The film serves as a follow-up to both the 2010 Karate Kid remake and the series Cobra Kai, bringing together the franchise’s legacy stars .
Stanley will next be seen in the upcoming film Pretty Babies. In that movie, she will star opposite Ashley Benson, Emily Alyn Lind, and Madelaine Petsch .
Other Cast Members Joining the Poser Series
Stanley joins a cast that already includes rising and established talent. Daisy Jelley, known for her work in How to Have Sex and Geek Girl, is part of the series .
Annie Murphy, who won an Emmy Award for her role as Alexis Rose on the beloved series Schitt’s Creek, is also a lead cast member. Murphy has since starred in episodes of Black Mirror and other projects, bringing significant recognition to the new Netflix show .
The combination of Murphy’s acclaimed comedic and dramatic skills with Stanley’s rising star power creates a compelling core for the thriller.
