In Hollywood, there is one dominant voice. It is a white, male, straight gaze. When I talk about positive portrayals of black people and women, I'm saying complexity. I'm not saying goody-two-shoes, everything's okay. No. The positive view of me is to see me as I am: the 'good,' the 'bad,' the gray. That is a positive portrayal.

Positive characterizations are complex characterizations. That's all we need to know. They shouldn't be saccharine. They shouldn't feel like medicine.

You know, often films that are deemed positive, nobody wants to see them.

I am honored to be one of this year's Urbanworld ambassadors for the festival's 20th anniversary, joining my friend David Oyelowo. I have always had a special relationship with Urbanworld, back to my days as a festival publicist to previewing my earlier films and now as an ambassador.

Creativity is an energy. It's a precious energy, and it's something to be protected. A lot of people take for granted that they're a creative person, but I know from experience, feeling it in myself, it is a magic; it is an energy. And it can't be taken for granted.

Women have been trained in our culture and society to ask for what we want instead of taking what we want. We've been really indoctrinated with this culture of permission. I think it's true for women, and I think it's true for people of color. It's historic, and it's unfortunate and has somehow become part of our DNA. But that time has passed.

The way that we're consuming what we watch. Netflix, binge-watching, destination agnostic were not terms. It was about networks, times, dates. Even with feature films, you had to see it this way, in this capacity, at this time. All that has changed. Now it's really about the story. It's a gift that I became a storyteller at this time.

You could make the most beautiful film, and that weekend it's raining too hard on the East Coast, and no one goes out. Artists should have a chance to do it again. That's the challenge: Women artists don't get a second chance. People-of-color artists don't get a second chance. You're put in director's jail, and that's a wrap.

I want more girls to be able to see themselves behind the camera creating images we all enjoy, and I want to call attention to the fact that women directors are here all over the world.

If, in 2014, we're still making 'white savior movies,' then it's just lazy and unfortunate. We've grown up as a country, and cinema should be able to reflect what's true. And what's true is that black people are the center of their own lives and should tell their own stories from their own perspectives.

Art is something that grows and breathes and lives, and it shouldn't be predicated on the success of box office - but it is. But within that, you have to give people a chance to find their voice, to play, to continue to create.

There was a time when I was knocking on doors and concerned with being recognized in dominant culture. I've found a space where the terrain is different, where I'm embraced by people like me, and where I'm building new ways of doing things, as opposed to trying to insert myself in a place that might not be welcoming.
