You can watch The Good Sister primarily on Amazon Prime Video, where it’s available to rent or buy. Depending on which version of the film you’re after-the 2014 thriller or the 2025 release-there are a few other free and paid options too.
The 2025 version
The newer The Good Sister (2025), a drama about a woman whose sister moves in and starts undermining her marriage, is currently available on:
- Amazon Prime Video – rent or purchase (HD, typically around $3.99–$4.99 to rent, $9.99–$12.99 to buy, prices vary by region).
- Apple TV – also listed for rent or purchase in the US store.
As of now, there’s no indication it’s included with a standard Prime subscription or available on Netflix in major markets; it’s a transactional title (pay per view) rather than “free with subscription”.
The 2014 version
There’s an earlier, similarly titled thriller, The Good Sister (2014), about a couple whose marriage is tested when the wife’s long-lost twin sister appears. This version has wider free and ad-supported availability in some regions:
- Tubi TV – free with ads (US and some other countries).
- The Roku Channel – free with ads.
- Hoopla – free with a participating library card.
- Amazon Video – rent (often around $0.99) or buy (around $2.99–$3.99).
- In Australia, it’s also listed on 7plus (free with ads) and Hoopla in addition to Prime Video.
How to make sure you’re watching the right one
Because there are multiple films with the same or very similar titles:
- Check the release year (2014 vs 2025).
- Look at the plot summary :
- 2025: sister moves in with her sibling and spouse in Atlanta, creating tension and seduction.
* 2014: wife discovers a long-lost twin; husband becomes involved with the sister, who turns out dangerous.
If you tell your streaming app or store which year you want, you’ll avoid ending up with the wrong film.
