18-year-old Mark wakes up in a parallel world where no one knows who he is - not his family, friends or girlfriend - and discovers that he and all the people he loves will soon die a painful death.

How to Watch Mark's Secret to Eternal Life Legally and Safely

If you want to stream Mark's Secret to Eternal Life 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 Mark's Secret to Eternal Life 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.
