Viewing Movies Offline
For rental movies, it's difficult to find services that allow you to view them offline. However, if you rent movies from the Play Store, you can do that. After you rent one, you can download it and "pin" it to one device. Then you have 30 days to start watching the movie. Once you start to watch, you have 24 hours to watch it as much as you like. After those time limits, the movie will no longer play.
