Gatekeeper

Patrolling a popular tourist destination of steep cliffs that plummet into the Sea of Japan, a retired police officer vigilantly intercepts troubled souls looking to jump, his count of lives saved now over 500.
How to Watch Gatekeeper Legally and Safely
If you want to stream Gatekeeper 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 Gatekeeper 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.
