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.

I care about people. In the end, I think they feel it. It comes across, regardless of the character I'm portraying.

The other night I was walking down the stairs behind one of my daughters. I was tired, and she was goofing around, you know like kids do, doing all this stupid stuff on the stairs. And I was thinking, please just go down the stairs and let's get you to bed. It's after your bedtime. I've had enough for one day. And then I sort of caught myself. I snapped out of it. I was like, 'dude, you should be dancing down the stairs behind her'!

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.

In a lot of films, they're showing more complete, developed characters of diverse ethnic backgrounds. The larger concern is to be able to tastefully explore the stereotypes, and still move past them to see the core of people.

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.'

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