Julieta Zylberberg is lightyears ahead…

The 38-year-old Argentine actress has been cast as a series regular opposite Sissy Spacek and J.K. Simmons in Amazon’s genre-bending drama series Lightyears, a co-production between Amazon Studios and Legendary Television.

Zylberberg will star alongside fellow cast newcomers Adam Bartley, Chai Hansen, Rocío Hernández and Kiah McKirnan.

Written and co-executive produced by Holden Miller, Lightyears follows Franklin and Irene York, played by Simmons and Spacek, a couple who years ago discovered a chamber buried in their backyard that inexplicably leads to a strange, deserted planet. They’ve carefully guarded their secret ever since, but when an enigmatic young man enters their lives, the Yorks’ quiet existence is quickly upended — and the mysterious chamber they thought they knew so well turns out to be much more than they could ever have imagined.

Zylberberg will portray Stella, a single mother living in rural Argentina, trying to raise her teenage daughter, but also burdened by a dark family secret.

Hernández is Toni, Stella’s daughter, a shy teenager who, wanting more from life, starts to resent her protective and secretive mother.

Daniel C. Connolly serves as showrunner. He executive produces with Mosaic’s Jimmy Miller and Sam Hansen. Philip Martin is executive producer and producing director for Season 1. Juan José Campanella will direct and executive produce the first two episodes of the series, scheduled to begin filming later this year.

Zylberberg won the Silver Condor Award for Best Actress in 2011 for her role in the film The Invisible Look. Her most recent work includes the film El Perro que no calla, and the television series Post Mortem and Separadas.

Argentinian actress Hernández has appeared onstage in theatrical productions in Buenos Aires such as Next to Normal and Juegos, ¿cuál es tu limite? Her recent television work includes the Argentinian series tierra de amor y venganza and the miniseries La caída.
