Non-Stop is, appropriately enough, a non-stop thrill ride full of twists, turns and narrative barrel rolls.
The key plot finds Liam Neeson's air mashall beseiged by a killer on the plane - a killer who forewarns him of each imminent death with a psychotic text alert.
But what if that killer was secretly a 13-year-old girl? Would Neeson and co-star Julianne Moore know their ROFLs from their FMLs?
We (rather stupidly) quizzed them on their text and internet acronym knowledge.
Non-Stop is in UK cinemas from 28 February 2014.
