Dark Castle and Warner Bros are in negotiations to sign Liam Neeson up to star in the upcoming movie Non Stop. Neeson would play the role of an air marshal on a domestic flight in what is being described as a contained, gritty action thriller.

Little is known about the movie other than back in August, Dark Castle got the script from writers John Richardson and Chris Roach and that Alex Heineman, Andrew Rona and Joel Silver are set to produce while Jeff Wadlow is set to take the director chair.

Neeson is one of the box office's bankable names this year, at the moment he is staring with Sam Worthington in Jonathan Liebesman's Wrath of the Titans while earlier in the year he won admirable reviews for his role in The Grey.
