These days Liam Neeson mainly plies his trade in action films, knocking seven bells out of lowlifes and in Non-Stop he plays Bill Marks, a US air marshal who's not having a very good day. He's drinking too much, and has just boarded a flight from New York to London when he begins receiving a series of bizarre text messages. The texter claims he'll kill a passenger every 20 minutes if Bill doesn't persuade his bosses to wire $150million to an undisclosed account. Marks thinks it's a hoax, but when the first body turns up he realises he's up against it.
A flimsy idea is well fleshed out by director Jaume Collet-Serra, and Neeson is easy to take seriously as a hard nut. There are enough twists and turns to make Non-Stop an enjoyable thriller.
