V for Vendetta
Probably the best line ever created for a movie.
"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 and vanished.
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, so let me simply add that it's my very good honor to meet you and you may call me V."
In the movie V for Vendetta, a monologue for V's introduction to Evey, containing 49 words starting with the letter "V".
It can't get any better when Hugo Weaving is the one who is giving the speech.
One word enough said... "Cool".
Heck... the monologue is longer than what I have written myself here.
