Is it that one where they're in the bunker-type building with the big TV/Window, counting down till the end?
If I knew the world was going to end, I'd probably just sit and watch DVDs.
The TV would be all news. The net would be jammed or crashed by "Well, even if they can trace it, I'll be dead tomorrow" hacking and cracking. The radio would be minute-by-minute updates. The streets would be rioting. The clubs-n-pubs would be full of drunken revellers who would resort to rape and murder just for the hell of it. And everything worth stealing would probably be in use or destroyed by rioting.
So, assuming the power was on, I'd watch DVDs.
