Monaghan plays a female truck driver who lives a careless life with no responsibility until she has to take in her estranged 11-year-old son after his father (Bratt) is hospitalized.
Monaghan, who just signed to star with Shia LaBeouf in the D.J. Caruso-directed “Eagle Eye” for DreamWorks, sparked to the script when it was submitted to her early. She attached herself before the film went out for financing, and she went so far as to get training and a license to drive a tractor-trailer.
Monaghan, who stars this fall in “The Heartbreak Kid,” “Gone Baby Gone” and “Men of Honor,” will be an exec producer of “Trucker” with John Allen, Robert Kessel, Pam Hirsch, Ed Hart, Bruce Lunsford and Frank Frattaroli.
Mottern, a former Nicholl Fellowship winner who once produced the Slamdance Film Festival, has written and directed docus for BBC and other networks.
