While the character of Idi Amin and some of the events surrounding him in the film are mostly based on fact, Garrigan is a fictional character. Foden has acknowledged that one real-life figure who contributed to the character Garrigan was English-born Bob Astles, who worked with Amin.[4] Another real-life figure who has been mentioned in connection with Garrigan is Scottish doctor Wilson Carswell.[5] Like the novel on which it is based, the film mixes fiction with real events to give an impression of Amin and Uganda under his rule. While the basic arc of Amin's rule is followed, the events in the film depart from both actual history and the plot and characters in Foden's novel.
In real life and in the book, Kay Amin was impregnated by her lover, who was a Ugandan physician (given a different name in the book than in real life). She died during a botched abortion performed by him, and he subsequently committed suicide.[6] Astles said in a lengthy interview for The Times with the journalist Paul Vallely that her body was dismembered by her lover so it could be hidden and was then sewn back together on Amin's orders.[7] Amin never had a son named Campbell.
Contrary to the wording of the film's coda stating, "48 hours later, Israeli Forces stormed Entebbe and liberated all but one of the hostages", three hostages died during Operation Entebbe. The body of a fourth hostage, 75-year-old Dora Bloch, who was killed by Uganda Army officers at a nearby hospital in retaliation for Israel's actions, was eventually returned to Israel.[8] The murder of Dora Bloch is depicted accurately in the book but not mentioned at all in the film. Also when the non-Israeli hostages were released, they are seen being flown out of Entebbe, Uganda to Paris, France on an Antonov An-12 aircraft, but in real life the non-Israeli hostages were flown to Paris on a chartered Air France Boeing 747.[9][10]
According to Foden, the film's depiction of Amin is comparable with the Shakespearean character Macbeth, whom he had in mind when writing the novel.[11]
