Is this the same film which sparked controversy a while back with their poster advertising campaign? I remember seeing some interesting movie posters of people 'trapped' such as one which looked like a bus-stop ad which made it look like someone was trapped against the window by some concrete or something.
If so, I was interested just based on the fact that they posters looked pretty good, nice to have someone try and push things a bit, even if it is controversy for the sake of publicity. Gotta mess with the status quo everynow and then...
I hadn't heard of this one before the press release hit my box. It looks like a pretty serious story. For some reason, people who make thrillers always get campy at some point (think, "Sliver") and this didn't give me that vibe.
