Reading the cast credits, and having seen the film...

Rating: 8/10 (4 May 2006)

***POTENTIAL SPOILERS*** It is unclear to me how the hijacker actor credits could be so low and/or non-existent.
The major draw of the film was how it all fit together. Cast and crew did this to near perfection.
Especially the motivations of "thems that would do such a thing."
You cannot bring to the screen the events of 9/11, and particularly that flight, a day on which I was en route to Baltimore, between 0800 and 1000 CDT, and not a whit was spoken on our flight about what happened, without showcasing the actions of the hijackers.
These actors did a Great job in maintaining the issues that the hijackers probably had, which enabled the passengers to be heroes.
Without making the hijackers the story, the actors portraying them did a great job. They weren't given their due.
