This depiction, chronicling in real-time the story of "United 93", is first rate and is so far ahead of any other movie that reflects on that tragic day, that other (Hollywood type) productions, which doubtless were more concerned with making money using 'high profile actors', should feel more than a bit embarrassed. This film IS believable. That may be stating the obvious, given what happened, but the use of relatively unknown actors and indeed, featuring actual staff from some of the agencies involved that fateful day give the film a sense of realism that is frighteningly tangible. I found it extremely difficult to fault any aspect of it - with the exception being the passenger/pilot who is given the only poor line to deliver in the entire film when he states, "Something is wrong here" when passengers are lying either dead or injured and there is a terrorist holding a bomb trigger, but that is a minor criticism. Everyone involved, production crew, cast etc deserve huge credit for the piece of work they have produced, which is a worthy testament to all those who lost their lives that day.
