Fox has added more heft to its remake of ITV’s dark crime drama “Broadchurch” with the casting of Anna Gunn and Jacki Weaver in key roles.

The Shine America series will be titled “Gracepoint” for its Fox run, skedded to bow next season as a limited series entry. Production on 10 episodes is set to begin in January.

Gunn (pictured left), fresh off her Emmy win for “Breaking Bad,” will co-star opposite David Tennant as Det. Ellie Miller, who reluctantly works a murder case in a seaside town with the new partner who got the promotion she was expecting. Tennant will reprise his role from the original, which aired in the U.S. on BBC America, as the new partner.

Weaver will play Susan Wright, a mysterious woman who moves into the town’s RV park.

Landing Gunn for “Gracepoint” is a coup for Fox as the actress has been highly sought after following her career-making run on “Breaking Bad.” Aussie thesp Weaver is a two-time Oscar nominee who starred in a CBS comedy pilot this past spring, “The McCarthys.”

“Broadchurch” creator Chris Chibnall is penning the first episode of “Gracepoint” and will exec produce with Shine America’s Carolyn Bernstein, showrunners Dan Futterman and Anya Epstein and Kudos’ Jane Featherstone.

Gunn is repped by UTA; Weaver is with ICM Partners.
