Liam Neeson continues to cash in on his status as a late-blooming action star by reteaming with Unknown director Jaume Collet-Serra for a thriller that takes place almost entirely at 40,000 feet. Neeson plays a U.S. Air Marshal who finds himself in a tight situation when an unknown stranger starts killing off innocent people on his flight. The premise is intriguing, but like most mysteries that take place on a plane, I suspect the twists will ultimately be underwhelming (especially since it was written by an editor and producer from the reality show Big Brother). Still, if you enjoy watching Liam Neeson growl at bad guys for 90 minutes, this should probably do the trick. Non-Stop hits theatres on Feb. 28th; check out the trailer after the jump and see what you think.
