Click here for a video version of this review: https://youtu.be/LemgSqyBgUM Wagner Moura first came to my attention as one of the stand out parts of the excellent Netflix series Narcos. We went on to watch him in the two brilliant Elite Squad movies and so the trailer for Sergio made me sit up and take notice. He is a fantastic actor, and the chance to see him in a political thriller based on a true story got my attention. Sergio Vieira de Mello was a Brazilian UN diplomat who played a key role in events in East Timor and Iraq in the late 1990s and early 2000s. Here's the official description of the movie: A sweeping drama set in the chaotic aftermath of the US invasion of Iraq, where the life of top UN diplomat Sergio Vieira de Mello hangs in the balance during the most treacherous mission of his career. Real life stories are often more interesting than fiction, and the life of de Mello was certainly very interesting. Right at the start of the movie, an event happens and then in the aftermath of that, Sergio reflects back on the key points of his life, from his work in East Timor in establishing a government there, to meeting his partner Carolina Larriera, to his arrival in Baghdad. The movie uses flashbacks quite well to tell its story, and in those flashbacks, enough information is given so that you can get an adequate grasp of what's going on. A lot of regionally specifically history and politics is included in these, but its done in such a way that the key points are communicated, just enough to help you understand the backdrop for that part of the story. I think it focuses a little too much on the relationship between Sergio and Carolina, its much more prominent than the trailer shows, and while it is an important part of Sergio's story, I did think it distracted a bit from the UN work that he was working so hard to implement. Overall, this was an absorbing film that adequately tells the story of one man trying his best to bring some change to the world.
