Trivia: The Last King of Scotland
- Billing Displacement: Forest Whitaker is billed first even though James McAvoy plays the central character (and therefore has considerably more screen time).
- Enforced Method Acting:
- For the scene early on where Idi Amin speaks before the cheering crowd of villagers, the filmmakers didn't have to tell the extras to react that way... because they all believed that Forrest Whitaker really was Idi Amin.
- The director decided to use local Ugandan children as extras for a scene where James McAvoy's character is giving vaccinations. Of course, the director did not tell the children or their parents/other adults with them that the syringes were just props. Many of the children thought they were really going to get shots, so their apprehension and nervousness is completely real.
- Fake Nationality: American Forest Whitaker as Ugandan Idi Amin.
- Hey, It's That Guy!:
- Promoted Fanboy: James McAvoy loved The X-Files as a teen and fancied Agent Dana Scully, so he found it intimidating to work with Gillian Anderson, whom he had to kiss in one scene.
- Retroactive Recognition: James McAvoy is best known for portraying the younger Professor X in the X-Men movies.
- David Oyelow, who plays Garrigan's medical colleague, would go on to play Martin Luther King (the real life inspiration for Professor X) in Selma, making their pairing in this movie a little eerie.
