Grey's Anatomy actor Jesse Williams is the latest big-name star to be cast in Hulu's Little Fires Everywhere, TV Guide has learned.

Hulu's limited series based on the bestselling novel by Celeste Ng also stars fellow Shondaland mainstay Kerry Washington, as well as Reese Witherspoon and Joshua Jackson.

According to Deadline, which first reported the news, Williams is set to play "wealthy Wall Streeter" Joe Ryan, who along with his wife, Madeline, turns to an unlikely source to help start their family after years of struggling with infertility. The story follows a single mom and her teenage daughter whose lives become entangled with a picture-perfect family.

Williams is best known for playing suave surgeon Jackson Avery on Grey's Anatomy and recently appeared on the big screen in Random Acts of Violence, which debuted in theaters last month.

Little Fires Everywhere is being developed and written by Liz Tigelaar (Casual), who will serve as showrunner. Witherspoon and Washington are also executive-producing the series. Cast members also include Rosemarie DeWitt, Jordan Elsass, Gavin Lewis, Megan Stott, Lexi Underwood, and Jade Pettyjohn. Hulu has yet to announce a release date for the limited series.
