Nuclear Now is a 2022 American documentary film, directed and co-written by Oliver Stone. The movie argues that nuclear energy is a solution needed to fight climate change because other renewable energies by themselves will not be sufficient in time for the planet to obtain carbon neutrality before climate change becomes irreversible.

The movie is based on the book A Bright Future: How Some Countries Have Solved Climate Change and the Rest Can Follow written by the US scientists Joshua S. Goldstein and Staffan A. Qvist. Goldstein co-authored the screenplay together with Oliver Stone. Producers include: Stefano Buono, Isabelle Boemeke, and Jon Kilik.

The documentary premiered out of competition at the 79th edition of the Venice Film Festival. Stone and Goldstein later also pledged for their propositions at the 53rd World Economic Forum 2023 in Davos, Switzerland. It features one of the final film scores of Vangelis.
