Liam Neeson continues his bizarre transition from Oscar-winner to action star with Non-Stop, a ludicrous, yet undeniably entertaining mile-high thriller that re-teams Neeson with Unknown director Jaume Collet-Serra. Bill Marks (Neeson), a Federal Air Marshall with a troubled past, is forced to spring into action when he starts to receive text messages threatening passengers aboard his transatlantic flight from New York to London. The vast amount of implausibilities contained within Non-Stop’s script are enough to render it a dumb waste of time, even without taking into account the horrendous dialogue, paper-thin supporting characters and poor final payoff. But both the pace and direction are tense enough to provide moderate thrills as the narrative twists and turns, and Neeson dedicates himself wholeheartedly to the role of Marks, a man with many layers, each as transparent as the last. It’s serviceable fluff, but a willingness to suspend disbelief is necessary.
