When he learned he would be playing Ugandan dictator Idi Amin in a movie, actor Forest Whitaker decided to first find out how closely they were related.
He explains, "I went and got DNA tested for my African ancestry because I wanted to see where I was from.
"I found out I was from Nigeria on my dad's side and Ghana on my mom's side. So then I went back there when I went to Africa.
"I didn't expect that I would go to East Africa first, but in a way I was going back to the source, back to the origin of man." [Link]
