It was probably made within the last couple years. We just watched a trailer for it on a rental DVD last night but forgot the name and the now the DVD is back in the post. Anyway, it looked like a suspense movie, there's an explosion in downtown LA and the husband is trying to reach his wife after she leaves the house. He's not sure if it's terrorists, the army shows up in chemical suits, the air is thick with smoke....there's no attempt during the trailer to explain the plot, just capture the mood. Apparently it got good reviews and there's a twist at the end? Any ideas of the title, it looks like a good one to rent? Cheers!
