Remember, remember, the 5th of November,
The gunpowder treason and plot

Should ever be forgot.

*noddles* I'm kind of surprised I even caught this. It might even of been just a coincidence, but the X was symbolic in the movie, and I'm pretty sure their was more to it then just the gunpowder treason (at least in the movie) or maybe I'm thinking of something completely different and they used that reference for no particular reason in the movie. Anyway, it was an interesting thing to see. I've never seen something like this before.

It was based with an idea of the peoples freedom from their government.
the government seeks to hold us down, to make us think we need it. when in actuality, its the government that needs us.

V said it quite adequately: "It is not the people who need to fear the Government, rather the Government who should fear its people."
