Okay, I promise I'm not promoting a film or anything. But I saw the trailer for "I Am Legend," coming out this winter, starring Will Smith. It's based on the novel of the same name by Richard Matheson, and there have already been two adaptations of it: "The Last Man On Earth" in 1964, starring Vincent Price, and 1971's "The Omega Man," with Charlton Heston (thanks, IMDB!).

Anyway, the movie looks pretty cool. Basically, Will Smith has spent the last decade as the only man left in Manhattan (or is he???, etc.).

But watching the trailer, what really struck me was the notion of a New York City without anyone to take care of it or to make it run. As I wrote about a few days ago, the city would pretty quickly fall into disrepair.

Check it out for the scenes of a weedy, overgrown Times Square and empty, crumbling streets through the city.
