Middle-aged Gerald Kingsland advertises in a London paper for a female companion to spend a year with him on a desert island. The young Lucy Irving takes a chance on contacting him and after a couple of meetings they decide to go ahead. Once on the island things prove a lot less idyllic than in the movies, and gradually it becomes clear that it is Lucy who has the desire and the strength to try and see the year through.

How to Watch Castaway Legally and Safely

If you want to stream Castaway 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 Castaway 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.
