"Civil War" premiered in North America last Friday and led the box office that weekend. Directed by Alex Garland ("Ex Machina"), it focuses on 4 journalists in an armed conflict.

It takes place in the United States of an imprecise future, with the U.S. divided by a new Civil War. "Where the film fails a little is precisely in that relationship between the colleagues," says the author of the script, who is also the director of "The Handmaid's Tale" and "The Descendants." "The film is not a simple fictional action film because it includes a group of journalists, war reporters, who risk their lives covering the clashes," he says. "It's a film about the relationship between journalists and the people they work with," adds the author.
