A few years[!] ago, there was a trailer on io9 about what would happen if the earth stopped spinning and everyone who could lived in the one city where the sun shined all the time. The trailer showed a caravan through a long tunnel where people could get smuggled in for the right bribe. Then everyone put on welding goggles, the door at the end of the tunnel opened, and BRIGHT sun showed on the city ahead.

The name of the concept trailer would be much appreciated. Also, did this ever get to the next level of film development by any studio? If not, lets kickstarter it.
