According to Deadline, Netflix’s limited series Zero Day has stopped production. The series, executive produced by Robert De Niro (Taxi Driver, Goodfellas), is another series suffering as a result of the writer’s strike.

In the series, De Niro stars as Mullen, a man pulled from retirement to lead a commission that investigates a global cyber attack. The term Zero Day is a term that describes security holes that hackers can exploit. The IMDB description of the series reads, “In the midst of crisis: how can we discover the truth when it seems that the world is being destroyed by uncontrollable forces? Also, to what extent are conspiracy theories our own inventions or products of our imagination?”

Lesli Linka Glatter (Now and Then, The Proposition), president of the DGA, serves as the series’ executive producer and director. The series is created by Noah Oppenheim (The Maze Runner, Allegiant), Michael S. Schmidt (Tatort, Police Call 110), and Eric Newman (Children of Men, In Time). Edi Gathegi (Caged, The Blacklist: Redemption), Joan Allen (Face/Off, The Bourne Ultimatum), Connie Britton (Nashville, Friday Night Lights), Jesse Plemons (Breaking Bad, The Power of The Dog), and Lizzie Caplan (Fatal Attraction, Now You See Me 2) are starring alongside De Niro.

On June 7th, the 37th day of the WGA strike, with a potential SAG-AFTRA strike looming overhead, Zero Day sent home its cast and crew. No return date has been set. With AMPTP negotiating with SAG-AFTRA and writers picketing, September has been suggested as a possible return date. However, no one can say for sure.

Zero Day is part of a deal Netflix has with Grand Electric Productions. Other than Glatter, the series is executive produced by Newman, Oppenheim, Schmidt, De Niro, and Johnathan Glickman (Rush Hour, The Count Of Monte Cristo) for Panoramic Media.
