English born Joan Stanley, a Soviet and communist party sympathizer, becomes employed as a British government civil servant, and gets recruited by the KGB in the mid 1930s. She successfully transfers nuclear bomb secrets to the Soviet Union (Russia), which enables them to keep up with the west in the development of atomic weapons, and remains undetected as a spy for over a half a century.

How to Watch Red Joan Legally and Safely

If you want to stream Red Joan through reputable and legal services, there are a few good options depending on where you are. Subscription platforms like HBO Max, Disney+, Netflix, Amazon Prime Video, and Apple TV+ sometimes carry Red Joan films or related DC titles—though availability depends on your country.

If you’d rather not commit to a subscription, there are ad‑supported, free (but legal) platforms such as Tubi, Pluto TV, Peacock or Crackle (where available in your region) that occasionally host superhero films.

Lastly, don’t forget about library‑linked streaming options like Kanopy or Hoopla (if your library or university is registered), and official uploads by film distributors on YouTube—these can also give you legal access to classic movies.
