Historical accuracy?

Rating: 8/10 (14 December 2006)

Given that this movie is based on historical events, I'm wondering if anyone knows how accurate to history it was? Did it leave out anything important or fabricate anything? What did it modify? Why did Britain install Idi Amin only to do a 180 and try to oust if not kill him? -- Did Amin fool the British that well, or what didn't they like about his predecessor? Once world opinion turned against Amin, why wasn't there more effort to remove him from power--or was there? Was there really a young Scotsman (or other white guy) who got so close to Amin? Was he able to expose anything to the world after escaping (or didn't he)? Did Amin ever face trial after leaving power in 1979--did the US, UK, or UN make any attempt to bring him to justice? Why would Saudi Arabia give him refuge? Was Amin allied with other murderous dictators like Robert Mugabe?
I thought Forest Whitaker and James McAvoy were great in this film. I'd suggest for people who like it that they might also want to see Lumumba, which is similar but has some key differences.
