I went and saw this yesterday at the movies. It was a very strong and powerful movie. The acting was great! 3 of the side characters were from recent TV Shows including two of my favourites. the shows were 24, LOST and Without a Trace.
The movie was very Sad and Emotional. I hadn't realised what it would be like just standing under the towers after the first plane hit and what it was like for the two men the movie's based on who were 20 feet under the rumble.
