I never acted in anything I've directed but I have produced a number of films and I have acted in some of the movies I've produced. Usually with first time filmmakers and pushing a move forward I have played a small role but never the lead.

Stereotypes do exist, but we have to walk through them.

There's a thing you confront when you're going into something new and you come to this sort of abyss, and then you push yourself. It makes you try different things.

I think the biggest thing that motivates me when I'm choosing a part is a role that will help me continue to grow as a person and as an artist, and a role that will deepen my understanding of humanity, and my connection to it.

There are people [in Uganda] who hate Idi Amin, a small amount. And then there are the people who really admire him, like a hero. And then there's a large group who say, 'We know that all these murders and atrocities occurred, but he did all these great things.'

As an artist, it's a great opportunity to play a character like this [Ugandan dictator Idi Amin in The Last King of Scotland]. And then, as a person, I had never been to the African continent. So, I knew, personally, it would reshape me.

I stay true, because whatever the project is, I'm still looking for inside of that character.
