Where to watch Zero Day: Netflix, from February 20, 2025.

Zero Day is a gripping new limited series created by Eric Newman (Griselda, The Watcher, Narcos, Narcos: Mexico) and Noah Oppenheim (Jackie, The Maze Runner, The Thing About Pam). The intense and suspenseful show centers on a widely admired former U.S. president, portrayed by Robert De Niro, as he spearheads an investigation into a devastating nationwide cyberattack while confronting his own inner struggles.

De Niro appreciates that Mullen’s ethos is to just tell it straight. “That’s the spine of my character in the show,” said De Niro. “Don’t dodge anything. Don’t play games. Be honest about what’s going on so that the public knows what’s going on.”
