Also, in the longer previews he's on the phone a lot, dealing with his clients or whatever (it appears he's a ticket scalper). He's sort of hanging out by the phone, and I got the impression the phone was one he used to do "business" with.
I wondered what happened to this movie.. I saw previews almost a year ago, and then it disappeared. I didn't make the connection to the D.C. snipers... but I'm glad it's coming out soon!
