Liam Neeson has become the action hero of February. Since "Taken", he has become the go to actor to save the February movie blues. At this point, it doesn't matter how ridiculous the plot or dialog, Mr. Neeson will save the day.
"Non-Stop" is pretty ridiculous but Mr. Neeson takes the film very seriously and finds a way to rise above the poor material and sell this story of a mid-air crisis. The film is silly but it does have one thread of suspense going for it, trying to figure out who is behind the plot to kill a passenger every 20 minutes. There are plenty of suspects on the crowded airliner.
Julianne Moore co-stars probably because she needed to make a car payment or was behind in her mortgage. She is too good an actress to waste her time in this "blink and it's gone to cable" movie. And if co-starring wasn't bad enough, her character disappears for most of the final act. Another waste of talent is the recent Academy Award winner, Lupita Nyong'o. She plays a flight attendant with almost nothing to do or say.
To make the most of this story, skip the film and re-watch the trailer. All the action and suspense are right there to enjoy for three minutes and it's free.
