Sarah Chalke will star opposite Katherine Heigl in Netflix’s adaptation of Kristin Hannah’s novel “Firefly Lane,” the streamer confirmed to TheWrap.

The 10-episode “Firefly Lane” adaptation tells the story of two inseparable best friends and their enduring, complicated bond, spanning four tumultuous decades. Hannah will serve as the show’s co-executive producer.

Heigl will play Tully Hart, who is described as a force of nature: magnetic, ambitious, reckless, and fiercely loyal, according to Netflix. Still bearing the scars of a traumatic childhood, she is dogged by inner loneliness, even as she goes on to fabulous fame and fortune as a journalist and talk show host. Hart’s saving grace is her best friend and soulmate, Kate, with whom she shares an unshakable bond, over the course of four tumultuous decades.

The “Scrubs” and “How I Met Your Mother” alum will play Kate Mularkey.

Here is the official description of the character from Netflix: Awkward and shy, Kate Mularkey has always been in the shadow of her best friend, legendary talk show host and journalist Tully Hart. With an endearingly self-deprecating wit, Kate is often underestimated, but she’s fiercely intelligent and fiercely loyal. She has the biggest heart, and a hidden wild streak.

Maggie Friedman is showrunner. She’ll write and executive produce the streaming series. Other executive producers include Stephanie Germain and Lee Rose. Peter O’Fallon will direct and executive produce the first episode.
