The masks aren't of Guy Fawkes but of the character of the film. I think people should look up Guy Fawkes and his beliefs before choosing him as a 'hero'. His was a religious 'demostration' not political as such, he thought by killing those in Parliament including the Protestant King he could impose a Catholic monarch on the country. He wasn't for the people or democracy, wasn't even a hero, just another religious fanatic looking to impose his beliefs on others.
