The plaintiffs have accused Callaham for intentionally withholding emails and other correspondences from the WGA screen writing credit arbitration panel in 2009 that according to the plaintiffs reveal how very little Callaham was involved with The Expendables and demand reimbursements from Callaham for any payments made to him for his fraud credit in the two films.
