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 really wasn't even sure if I should continue acting. I would like try and figure out if I could be good enough to do it. It was like 10 or 12 years into my career before I felt like maybe I can do it. It was such a different time than now.

I started by studying Kiswahili to learn the dialect. Then, I studied tapes, documentaries, footage, and audio cassettes of Idi Amin's speeches. And I met with his brothers, his sisters, his ministers, his generals' all kinds of people, in order to try to understand him.

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.

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.

I found the people to be very kind and generous. It was unique because the crew was mainly Ugandan [filming The Last King of Scotland]. They had never done a film before. So, they were learning the process of making films, but at the same time they were also helping with the authenticity of the film.
