What is the Cast of Zero Day Season 1 Episode 1?

- George Mullen (Robert De Niro)

Because the series has not yet aired, the exact episode-by-episode cast breakdown is based on pre-release credits.
Who Plays the President in Zero Day?
There are two presidential characters in the series. Robert De Niro plays George Mullen, the former U.S. president who leads the Zero Day Commission. Angela Bassett plays President Evelyn Mitchell, the current sitting president who appoints Mullen. This distinction is important because some search results may refer to “the president” without clarifying which one.
According to Netflix Tudum, George Mullen is described as a hugely popular but complicated former leader, while Evelyn Mitchell is the current commander-in-chief. Both actors bring significant screen presence: De Niro is a two-time Oscar winner, and Bassett received an Honorary Oscar in 2024.
Is There a Zero Day Season 2 Cast?
Zero Day is officially a limited series (or mini-series), meaning it is designed as a single-season story. As of early 2025, there is no confirmed second season. Sources such as IMDb, Rotten Tomatoes, and Wikipedia all list it as a mini-series, not an ongoing show.
Although search queries for ‘Zero Day season 2 cast’ exist, no announcements have been made. If Netflix decides to renew the series, the cast could change. For now, the limited-series status is the only official information available.
