Keep an eye on official movie giveaways. Occasionally, studios or platforms like (free-with-ads section) or Vudu (Fandango at Home) offer the first film ( Fellowship of the Ring ) for free as a promotional tool for a new release (like The Rings of Power season premieres).

There are still legitimate ways to watch for free, but they require credit cards and calendar reminders.

Some free, ad-supported streaming services (FAST) occasionally license major films.

If you find a "free" source, check which version they are offering.
