There are things that make me excited about what I'm doing: Trouble the Water [the 2008 documentary Glover executive produced] on New Orleans, or something like Soundtrack for a Revolution, about the power of the music of the civil rights movement [which he executive produced in 2009]. Or Bamako, about the African debt crisis, a platform to discuss the experience of people who actually live it. All of these are important ways we can use film as a forum inviting people into a dialogue.

Mother Earth is in pain and ailing because of global warming.

We all know Reagan's legacy, from the Iran-Contra affair to the funding of the Nicaraguan military in which over 200,000 people died. The groundwork for the move steadily to the right happened with the Reagan administration. People want to elevate him to some mythic level; they have their own reason for doing that.

It's a misconception to believe that the resistance ended with the civil rights movement.

Remember, we're talking [in The Black Power Mixtape] about 1967, the year before [Martin Luther] King's assassination. We're talking about the emergence of black power, which is a discussion King mentioned in his last book, Where Do We Go from Here: Chaos or Community? We're talking about the meaning of black power and the possibility that it alienated our supporters, both white and black.

The black power movement was not a separation from the civil rights movement, but a continuation of this whole process of democratization.

Democracy is about criticism. I didn't elect Obama because he's a black; I voted for Obama because he was the right person at the time. Period. The exceptionalism of a black U.S. President is not important to me. It's what he does. And who he has at the table. And what he does to change the world - that's what's important.
