The five Oscar nominees for Best Documentary Feature this year show that the power of film can make a difference. One has changed policy at the Pentagon, another could change policy for Israel's occupation of Palestinian territories and yet another has blown up the career of a singer-songwriter nearly 40 years after his last album was released to little notice. The other two docs offer remarkably inspiring chronicles of positive activism.

Any of these films might be called important, necessary, compelling, astonishing and deserving of the Academy Award. However, while "Searching for Sugar Man" is the expectant frontrunner for the honor, it wouldn't be surprising if the Oscar went to "The Invisible War,""The Gatekeepers,""How to Survive a Plague" or "5 Broken Cameras."

Check out the guide on all these nominees below to understand why they're all worthy, as well as where you can see them for yourself.
