Is there anyplace on the internet where I can watch "Rent" for free?

Here ya go

Here are two sites that you can watch movies for free. I have been using them for about a year now, and they have very good choices. You might be able to find what you are looking for. Good Luck→
http://www.hulu.com/
http://fancast.com/

THANKS!

Just kidding, my link sucks. Try this one . You can either download it or watch streaming video.

I suggest you look around Hulu.com like @DixieRock suggested. It’s not advisable to talk about stealing media on Fluther. See this (from here).

I use this website all the time they have almost every tv show on there

hulu is also a really good one

I forgot one, (sorry about that) very good site tells you where to watch→
