How big is the average digital file of a movie?

Answer 1

Can range from 3 to 14GB usually. 14GB is usually for very high resolution 1080p videos @ 30 or 60 fps, and 3GB is the smaller 1280x720 at 30 fps (720p).

But you can't find these videos on the net usually. On the net you'll usually find videos that claim to be HD but that are in fact standard low-res videos that have been stretched, so you would really be downloading redundant information in that case. Be sure to check the comments if you download.
