The director of this film, Paul Greenglass, is known for his use of hand-held cameras (e.g. a couple of the Bourne flicks, United 93, etc.) and I know of one person who felt seasick while watching this film on the big screen. However, this a taut and well-acted movie (just the last several minutes of the movie alone increased my admiration for Tom Hanks’ acting prowess) that will keep you engrossed through its more than 2 hours.
