Yes, you can watch the movie again (and again!) if you start it within the 48-hour window.
Not true.
For some reason, some are actually 24hours now, but TV Shows are still 48 hours.. Weird.
So would i be able to watch it again and again in the 24 hour period?
I'd rent a lot more movies if the window was something longer than 24 hours... just let me comfortably finish watching the movie the next night if I fall asleep or get interrupted.
Heck, 24 hours + the run-time of the movie would be an improvement.
