When  troubled Air Marshall Bill Marks (Liam Neeson) boards a plane to London, he had no inkling that his flight would become the target of a malicious terrorist who has vowed to kill a passenger every 20 minutes if his demand of $150 million is not met. When the TSA tries to track down the account number he has given Bill, however, they find that the account is under Bill’s name. As Bill is suspected of staging the threat, and evidence continue to surface against him, the passengers must choose whether to trust the Air Marshall or figure out who the killer is before the entire plane is blown to smithereens.

Non stop asks the question: What do you do when someone screws with you 35,000 feet in the air? For Liam Neeson, the answer is quite simple. He deals with a*s using the type of skills he has become known for since Taken. Non stop is an apt title for this film, not because of the non stop action in the movie but rather because of the non stop guessing game that audiences must go through while the movie progresses. And this is something that I love about the movie because it gets audiences to think. There is no shortage of suspects in this movie — 150 of them to be exact. Heck, even Liam is not exempt from suspicion, and this draws people into the story. Of course, there are a lot of attempts to mislead viewers but in watching this film, one must be sharp and not miss even the smallest of clues lest they be convinced that the usual suspects are responsible for the chaos.

The action scenes are brilliant. Because there is limited space, fight choreographers maximized the use of hand to hand combat, which Liam Neeson performs so effectively that it gets tough to picture anyone, not even a group of able bodied men winning against him.

Non stop starts off a bit slow in order to establish the story but the 20-minute window for the killings seems to be just enough time for Liam to do his thing in between. But when the climax kicks in, it leaves no doubt that Non stop is a movie that means to entertain and deliver.

All in all, Unknown director Jaume Collet Serra did quite well in his second time to work with Liam Neeson. Non stop separates itself from other flight inspired movies by treading quietly but surely with a story that is interesting and intelligent, even going so far as to question  how secure the US’s security policies are — and utilizing great actors who deliver performances that keep the audiences guessing if they are in fact, heroes or villains for the entire 106 minutes of the movie. Oh, and did I mention that Julianne Moore (Hannibal, Game Change) and Downton Abbey’s Lady Mary Crawley herself Michelle Dockery are in this movie. Well, that just about upped the coolness quotient of this film, didn’t it?

As a moral lesson: Whether he’s on the side of good or evil, never mess with Liam Neeson. He played Ra al Ghul, Qui Gon Jinn, Jesus Christ, Oscar Schindler and Brian Miller for a reason. After seeing this movie, you will know why at his age, he is still one of this generation’s most formidable action heroes and badass extraordinaires.
