An Officer and a Spy is a 2019 historical drama film directed by Roman Polanski about the Dreyfus affair, with a screenplay by Polanski and Robert Harris based on Harris's 2013 novel of the same name. The name J'accuse has its origins in Émile Zola's article in l'Aurore in January 1898 in which the famous author accused many people of France of continuing to support the increasingly blatantly erroneous accusations against Dreyfus.
