I like to play complex characters and the duality, and trying to reach for the light, it's more interesting really. I've gotten to play so many types of guys and I just try to find the humanity in each one of them the best I can.

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.

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.

I certainly don' think I could've played the character [Idi Amin] the same way without being in Uganda. I loved working in Uganda.

In every project, I always look for the depth of humanity inside of it. I'm just trying to say if we can help in some way heal the equation with [Afro-Americans] what's going on with us as people.

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'!

I'm really excited that people are receiving my performance like this. It makes me feel good, because I've been working really hard. And this character [Idi Amin], I worked particularly hard on. But I don't want to get too caught up in it, because first of all, it could lead to a great disappointment. You never know what's going to happen.
