Wow.

Where did you find it?

I just googled for "V soliloquy" and surfed around till I found it on someone else's blog. :)

It's the kind of thing that really makes you love the English language!

"Voilà! In view, a humble vaudevillian veteran, cast vicariously as both victim and villain by the vicissitudes of fate. This visage, no mere veneer of vanity, is a vestige of the vox populi, now vacant, vanished, as the once vital voice of the verisimilitude now venerates what they once vilified. However, this valorous visitation of a bygone vexation stands vivified, and has vowed to vanquish these venal and virulent vermin vanguarding vice and vouchsafing the violently vicious and voracious violation of volition. The only verdict is vengeance; a vendetta held as a votive, not in vain, for the value and veracity of such shall one day vindicate the vigilant and the virtuous. Verily, this vichyssoise of verbiage veers most verbose vis-à-vis an introduction, so let me simply add that it's my very good honor to meet you and you may call me V."

The copies above aren't true to the movie, here's what's actually said:
