Before you download movies, ensure your iPad is running iOS 9.0 or later, and you have to install the latest version of the Netflix app. Launch Netflix on your iPad, and tap Movies in the menu bar to limit your search results to movies only. Tap on the Download arrow below your selected movie. If you can't see the Download downward arrow, this means the movie can't be downloaded. Then, it starts to download to your iPad. When it is finished, click the Downloads button at the bottom of the screen, and then you can tap Play to watch it.
