Zero Day had everyone talking when it was first announced, with many noting that Robert De Niro doesn't do many TV shows. I was intrigued to see him playing a troubled former President, as Netflix has a record for being pretty good with political thrillers.

De Niro stars as former U.S. President George Mullen. Part of his role includes leading the Zero Day Commission, an investigative group specializing in cyberattacks.
