Dark Castle has picked up Non-Stop, a thriller contained on an airplane, to be directed by Jeff Wadlow. Wadlow is best known for directing Never Back Down, though he has worked closely with Non-Stop producer Joel Silver in television on both Hail Mary and The Odds.

THR has the scoop and offers this in the way of a synopsis:
Plot details are being kept under wraps but the project is described by those in the know as a contained, gritty action thriller centering on an air marshall flying on a domestic flight.

Wadlow, who often does script work on his projects, is working with two unrepped writers to put the Non-Stop script together. Way to hang onto that indie cred, Wadlow.
