This gritty biopic recounts the life of brutal Ugandan dictator Idi Amin as seen by his personal physician. (Yes, Amin did at one point declare himself King of Scotland.) Forest Whitaker (fresh off "The Shield") gives a major performance, making Amin both monstrous and pitiful. The film's jarring camerawork adds to the thrilling nature of this ugly but absorbing tale. 121 minutes R.
