Roméo and Juliette are two young actors. They fall in love at first sight, move in together and make a baby. A love story and the founding of a home like millions of others. Except that their little boy, Adam, behaves abnormally. The young parents try hard to persuade themselves that everything is okay but, with the passing of time, they cannot delude themselves anymore : their son has problem. Their fears are unfortunately confirmed : Adam suffers from a malignant brain tumor. From now on, war is declared. A war against illness. A war against Death. A war against despair.

How to Watch Declaration of War Legally and Safely

If you want to stream Declaration of War 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 Declaration of War 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.
