‘The 100’ Casts ‘Allegiant’ Star in Mystery Role

Nadia Hilker to play new grounder character on CW post-apocalyptic drama

“Allegiant” star Nadia Hilker has joined the cast of The CW’s “The 100” in a recurring capacity, TheWrap has learned.

She will play a grounder, in what is described as an important role, though more details are being kept under wraps.

Hilker is currently set to appear in two episodes of the show’s third season and there is speculation she could play the role of Luna, a character who has been mentioned by name on the show since Season 1 but has yet to be seen.

The series is centered on 100 juvenile delinquents who are sent down to a potentially toxic Earth to test its habitability, and stars Eliza Taylor, Bob Morley, Marie Averopoulos, Paige Turco, Henry Ian Cusick and Isiah Washington.

Grounders are the native Earth population the delinquents have encountered and had a complicated relationship with in their months on the ground.

“The 100” is based on the book series by Kass Morgan and is produced by Bonanza Productions Inc. in association with Alloy Entertainment, Warner Bros. Television and CBS Television Studios.

Jason Rothenberg created the show and is the executive producer. The show was recently renewed for Season 4.

Hilker is best known for playing the role of Nita in “Divergent” threequel “Allegiant,” and she’ll reprise the role opposite Shailene Woodley in the franchise conclusion, “Ascendant.” She is represented by Management 360.
