Umbrella - The Movie

Umbrellas are everywhere.
Unescapable. Unavoidable. And un-livable(!?) without.

In the rain, people use them. In the sun, they're used too. All this umbrella business has been making me think, to and from work everyday, that there must be a movie in here somewhere.
And then it hit me:

Look at a sort of post-democratic 'V for Vendetta/Aeon Flux'-type world where some anarchists are the last stand against the evils of elitism. The central character's main trait is that he takes down the bad guys with an assortment of umbrellas:

As a Weapon -
-In arm to arm combat, made of steel.
-Turns into a gun (the spike is the exit)
-Shoots a web from the spindles around it.
-Shoots darts from the spindles around it.
-Shoots electric stunners from the spindles around it.
-An explosive one.

As Defence -
-A solid one which withstands bullets.

As Transport -
-To float down from a high building holding onto the handle.
-To slide across a rope by the handle (holding onto the spike).
-To sail downstream by sitting inside it (it would be comfortable).

As Protection -
-From the rain of course, d'uh.

I need a name, a title and then I'm basically there.
Any more ways to use the umbrellas?
