Add "Non-Stop" to that short list of films that you will never see as in-flight entertainment. Liam Neeson (making 60-something seem like the new 40) plays Federal Air Marshal Bill Marks, who is on a flight from New York to London when he receives an anonymous message on his cellphone telling him that a passenger will die every 20 minutes unless $150 million is deposited in an offshore account. When the authorities are alerted, Marks, an alcoholic ex-cop, seems as suspicious as anyone.
