With the MTA’s looming ‘Dooomsday Budget’ likely to wreak havoc for straphangers, this trailer for “Subhysteria,” a horror film set in the New York City subway system, couldn’t have been released at a more perfect time. And with the way the F has been running lately, the plot is starting to sounds a lot like our daily commute: “Sixteen people get stuck in a subway car in NYC for 36 hours, without communication, food, way to escape, and a fatal sensation that they are going to die.” It’s being released in Spring of 2009 and there’s even a blog detailing the frightening fiction.
