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've always wanted to do characters that would help me find my connection with others and connect all of us together. You always want the energy of the character, the spirit of the person, to enter you.

Because I was playing Idi Amin, who dealt with the colonisation issue, I became aware of this internalised conflict of what it means to be torn between cultures, what it means to be taken over by other cultures.

Trying to understand, inside, what it is to be Ugandan was crucial to the character, because there are Ugandan ways of doing things that I was trying to capture. Even if I had made this movie in South Africa, it would not have been the same, because it is so specific to Uganda.

I hope that audiences respond really positively. I think it's a very intense, entertaining film [The Last King of Scotland], because you're brought in on a fun ride, and slowly you fall into it as James [actor James McAvoy's character, Dr. Nicholas Garrigan] does. Nicholas is like the audience. I think it's a good ride for people. And you learn something, as well.

My parents moved to Los Angeles when I was really young, but I spent every summer with my grandparents, and I'd stay with my grandfather on the farm in Longview. He was retired from the railroad, and he had a small farm with some cows and some pigs. I remember part of my youth was feeding hogs and plowing fields and stuff, so that's a part of me.

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'!
