EXCLUSIVE: Stephanie Koenig (Lessons in Chemistry, English Teacher) has joined the cast of Apple TV‘s Platonic for Season 3 in a recurring role. She will play Alex, a lawyer who just began working at Charlie’s (played by Luke Macfarlane) firm.

From Nicholas Stoller and Francesca Delbanco, Platonic follows a platonic pair of former best friends approaching midlife (Seth Rogen and Rose Byrne) who reconnect after a long rift. The duo’s friendship becomes all-consuming — and destabilizes their lives in a hilarious way.

Season 2 picks up with everyone’s favorite pair of best friends as they contend with new midlife hurdles, including work, weddings and partners in crises. The duo tries their best to be each other’s rock, but sometimes rocks break things.

The cast also includes Luke Macfarlane and Carla Gallo.

Platonic is produced by Sony Pictures Television, where Stoller’s Stoller Global Solutions has an overall deal. Byrne, Stoller, Delbanco and Conor Welch executive produce, along with Rogen, Evan Goldberg and James Weaver for Point Grey Pictures.

Most recently, Koenig was a series regular and writer on the FX comedy English Teacher. She played history teacher Gwen Sanders. Before that, she also had a main role as Fran Frask, starring opposite Brie Larson in Lee Eisenberg’s Apple TV miniseries Lessons in Chemistry. Koenig also recurred in the Paramount+ TV miniseries The Offer and HBO Max’s The Flight Attendant. She is repped by Green Management, Paradigm Talent Agency and Ziffren Brittenham.
