Open Watch now, choose the service, and use its Download arrow in the phone or tablet app. Netflix, Prime Video, Disney+, HBO Max, Paramount+ and Apple TV all allow downloads on their mobile apps on most plans.
How much space
An hour of standard quality takes about half a gigabyte and an hour of HD one to two. An eight-episode season of Reacher fits on most phones with room to spare.
How long they last
Downloads stay in the network's app for a set period, usually a few weeks, and some services limit how many titles you can keep at once.
