My wife and I went to see the movie, United 93, tonight.  It's a very powerful film.  The show is done in real time so that you get a feel for how the events unfolded and the order in which the happened.  It's very gripping at times.  One thing worth mentioning...the air traffic controllers in the show actually play their own parts and are not actors.  They were the actual guys who were at the scopes when the tragedy played out.

From what I understand, the producer worked very closely with the victims' families so as to treat the events with the utmost respect.  I thought he did a very good job.
