Joshua Jackson has booked his TV follow-up to The Affair.

The Dawson's Creek favorite has joined the cast of Hulu's highly anticipated take on Celeste Ng's Little Fires Everywhere.

The eight-episode limited series follows the intertwined fates of the picture-perfect Richardson family and an enigmatic mother (Kerry Washington) and daughter (Lexi Underwood) who upend their lives. The story explores the weight of secrets, the nature of art and identity, the ferocious pull of motherhood — and the danger in believing that following the rules can avert disaster.

Jackson, who will be a series regular, will portray Bill Richardson, a Shaker Heights attorney who hails from modest means. Bill is the perfectly suited counterweight to his energetic and strong-willed wife, Elena (Reese Witherspoon), but when he agrees to represent their friends in a fiery custody battle, the couple begin to fight about more than just their challenging youngest daughter, Izzy (Megan Stott).

Little Fires Everywhere landed at Hulu following a multiple-outlet bidding war. Witherspoon's company, Hello Sunshine, snatched up the rights to the book before its publication and brought it to fellow star and executive producer Washington. Together, the actresses took it to writer Liz Tigelaar (Casual, Life Unexpected) to adapt and to serve as showrunner. ABC Signature will exec produce the project alongside Hello Sunshine and Simpson Street. Tigelaar, Lauren Neustadter, Pilar Savone and Lynn Sheldon will all exec produce.

Sources note that several outlets attempted to take the package off the table, but Witherspoon and those involved insisted on letting everyone hear the pitch as they mulled the right home for the project. (In a rare move, network execs went to the Hello Sunshine offices rather than producers hopping from network to network.) Little Fires Everywhere will be a co-production between ABC Signature and Hello Sunshine. It is the first project on which the latter has served as the studio.

Rosemarie DeWitt, Jade Pettyjohn, Jordan Elsass and Gavin Lewis round out the cast.

Jackson, repped by CAA, Anonymous Content and Hansen Jacobson, next appears in Netflix's Ava DuVernay drama When They See Us.
