Liam Neeson is taken with the Non-Stop script

Liam Neeson, recently in “The Grey”, will strap his butt-kicking boots back on for “Non-Stop”, a new actioner from Joel Silver’s Dark Castle Entertainment.

Variety says the John Richardson and Chris Roach written picture will center on an Air Marshall who encounters a threat mid-flight. “Never Back Down” director Jeff Wadlow will helm.

Neeson next appears, albeit briefly, in “The Dark Knight Rises”.
