How to download a movie, no strings attatched?

I want to download the movie Saw onto my computer (Macbook, it has to be a mac download) but not a .dmg file that doesn't work for my computer. I want a site that I can download Saw for free, no strings attached, I just click download and walla! I'm gonna put it on a hard drive and play it on my Ps3 so it has to work for that, anybody have a good free movie download site?
