Non-Stop

This solid but workmanlike thriller stars Liam Neeson as a veteran air marshal on a flight from New York to London who receives a text telling him a passenger will die every 20 minutes unless $150 million is transferred to a secret account. Tasked with finding the killer among his 200 fellow passengers, and aided by frequent flyer Julianne Moore and plucky flight attendant Michelle Dockery (Downton Abbey), Neeson plays a cat-and-mouse game above the Atlantic while trying to keep the body count to a minimum. The premise is intriguing, and director Jaume Collet-Serra (Unknown) delivers intermittent claustrophobic thrills, although he struggles to sustain momentum. It's not Neeson's most convincing action-hero performance, and he's not helped by a script that lays on the hammy dialogue a little too thick and stretches credulity to breaking point.
