Things aren't looking good for the world's population; as we multiply at an alarming rate there is not enough food, space... or sense. This intelligent film interweaves a fascinating 1960s rat experiment by Dr. John B. Calhoun with a slick snapshot of today's urban jungle.

How to Watch Critical Mass Legally and Safely

If you want to stream Critical Mass 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 Critical Mass 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.
