The movie is set in Rwanda in 1994. At the start of the movie you see a billboard advert for MTN, a South African cellular service provider that was not available in Rwanda in 1994.
In one scene Paul is listening to the radio and a broadcast of the debate about whether what was happening in Rwanda was considered genocide. During the conflict there was a news conference that was very similar to the one on the radio. One of the reasons that the US and UN would not label (or appear to label) the situation as genocide was that under legal obligations they would have had to act to prevent and punish the perpetrators if they said what was happening in Rwanda was genocide.
