The pitch sounds like Sunshine meets Zathura.

Hey, did you guys realize that asteroid is just steroid with an A in front, which usually implies "non"?

next, tetris the movie: the rise of the L block. this will be the struggle of freedom of the blocks against the reign of the L block. the square block, haunted by the deletion of the S block, will rise to the challenge against all odds and overthrow the L block.
I can has movie now?

I imagine this being the tale of two post-traumatic veterans of the Asteroid Battles, rehabilitating themselves in a shantytown colony and leaping out of their seat to blast apart anything that moves nearby, twitching furiously, spinning in one place, terrified to hit the thrusters in fear that they'll be unable to stop, peering suspiciously out the door wondering if they'll come back into the room from the other side.

"They say an asteroid man has three lives.  I'd give it all right now just to have one without the pain."

Then the government tells them they're needed again for one last suicide mission. To save Earth.

Ummmm.....that's the most generic description of a new movie that I've ever heard.  If you remove all of the "space" words, it could be a TV family sitcom idea.

I'll pay to watch this move if they don't have sound in the vacuum of space. Otherwise, I'll acquire it through "non-traditional means".
