How much data does a movie on netflix use?

How many MB of data will a 2 hour movie from netflix use on my iphone?

When I was using Netflix, one twenty minute episode used like, 80 data.

Probably 3-4gb.that's 3-4000mb in case you didn't know.depends on the quality

An entire movie would be alot… Not sure the exact number but you would want that over wifi.

It will depends on video quality. Higher quality uses more data. You can set your video quality in your Netflix account settings.

But typically, a two hour movie at normal quality will use around 600MB of data. At high quality (1080p HD video, for example), it will use closer to 5GB.
