I'm going to need to make a storyboard for this film, so we need to come up with a definite storyline, so here's how I'm guessing it could basically go, based on Paper Tiger's idea. Post anything yo think should be added to it, so well all agree on what we want to do:

Begins with a mansion/large building in the middle of the countryside at night, where we all live. A figure dressed in black is infiltrating the building, sneaking past guards, using gadgets, the usual. He gets into the high security room were the companion cube is stored, gets past the lasers, etc and snatches the companion cube. All this will be similar to scenes in films like the Pink Panther. He nearly gets caught by a guard or summat on the way out, and escapes. The next morning we all wake up and discover the disaster that has happened. The thief has left some evidence, so we begin to track him down. We find out he's staying the night in a nearby town, on the way back to his evil paymaster. A car chase ensues around the town, which ends in one of us getting shot by the thief as he holds a knife to the companion cube's neck. This makes us want to seek out revenge even more, and we follow the thief back to the villain's hideout. we break in very loudly, and a gun fight takes place between us and some guards. We find the villain, and there's a big gasp when we see who it is (need to decide who though). He presses a button, and the majority of us fall through a trapdoor or summat, the one person who is left has to make the decision between their friends and the companion cube, but somehow tricks the villain and manages to save both, but there is an anticlimax as the companion cube is tossed into the air and falls into the incinerator (slow-mo). This is all very sad, and ones of us accidentally hits the nuke button, and everything explodes. The End.

I was thinking, to display ourselves in the film, I could try and put a Flash animation over the top of a Gmod film, wadda you think?

Also, can anyone contact Paper Tiger? He should know that we're using his idea.
