One of my favorite movies is V for Vendetta, is a series of 9 comics written by Alan Moore which became a movie in 2006. And this movie has been widely criticized as praised.
The sinopsis is: "The story is set in Britain in the near future and after a partial nuclear war, with much of the world destroyed. In this future, a fascist party in power in the UK. A mysterious anarchist revolutionary nicknamed "V ", hidden behind a Guy Fawkes mask, begins an elaborate, violent campaign to overthrow the government and inciting people to take an anarchist society."
The Director of movie is James McTeigue with Hugo Weaving (V) and Natalie Portman (Evey), and this movie is filmed in UK, in 2006.
I like this movie because is "based" on the real histories about the dictatorship in the world, with a charismatic, powerfull, cruel and tyrannical leader with hes opponents. And the most important thing about the movie is the ability of the main character to construct the opposition.
The lesson of the movie is to overcome fear and work together.
