Did we watch the same movie? Or read the same comic? From its wiki:
“V for Vendetta is a British graphic novel written by Alan Moore and illustrated by David Lloyd (with additional art by Tony Weare). Initially published between 1982 and 1985 in black and white as an ongoing serial in the British anthology Warrior, its serialization was completed in 1988–89 in a ten-issue colour limited series published by DC Comics in the United States.”
It was british in the comic…
Plot summary of movie?
“Following world war, London is a police state occupied by a fascist government, and a vigilante known only as V (Hugo Weaving) uses terrorist tactics to fight the oppressors of the world in which he now lives. …”
British in the movie.
Now, to be fair, the screenplay was written by 2 Americans who loved the comic and it was directed by an Australian. Your downvotes are coming from you jumping onto the “amerikkka bad” train without any real connection here.
